Answer Key
1:
A
Solution: Logic: Next term = Previous term /4 2816 /4 = 704 704 /4 = 176. 176 /4 = 44. 44 /4 = 11.
2:
A
Solution: 113 113 * 2 = 226 -1 = 225 225 * 2 = 450 -1 = 449 449 * 2 = 898 - 1 = 897 897 * 2 = 1794 -1 = 1793
3:
A
Solution: P RODUCTIVIT Y = RODUCTIVIT.(First and last letters are removed.) R ODUCTIVI T = ODUCTIVI. O DUCTIV I = DUCTIV.
4:
A
Solution: First Number = 1 *2 *3 = 6 Second Number = 2*3*4 = 24 Third Number = 3*4*5 = 60 Fourth Number = 4*5*6 = 120 Fifth Number = 5*6*7 = 210 Sixth Number = 6*7*8 = 336. Alternatively , 2*2*2-2=6 3*3*3-3=24 4*4*4-4=60 5*5*5-5=120 6*6*6-6=210 7*7*7-7=336.
5:
C
Solution: Logic: First Term = 6. Second term = 6*2 -1 = 11. Third term = 11* 3 - 2 = 31. Fourth term = 31 *4 - 3 = 124 -3 = 121. Fifth term = 121*5 - 4 = 601. Sixth term = 601 *6 = 3606 - 5 = 3601 .
6:
B
Solution: Logic: Last Term *2 - 3 = Next Term. First Term = 7 Second Term = 7 * 2 -3 = 11 Third Term = 11 * 2 - 3 = 19 Fourth Term = 19 * 2 - 3 = 35 Fifth Term = 35 * 2 - 3 = 67 Sixth Term = 67 * 2 -3 = 131 Alternative Solution : Last term + 2 n = Next Term First Term = 7 Second Term = 7 + 2 2 = 11 Third Term = 11 + 2 3 = 19 Fourth Term = 19 + 2 4 = 35 Fifth Term = 35 + 2 5 = 67 Sixth Term = 67 + 2 6 = 131
7:
A
Solution: Logic: Previous Term * 3 - 2 = Next term. First Term = 8 Second term = 8 * 3 - 2 = 24 - 2 = 22 Third term = 22 * 3 - 2 = 64 Fourth term = 64 * 3 - 2 = 190 Fifth Term = 190 * 3 - 2 = 568 Sixth Term = 568 * 3 - 2 = 1704 - 2 = 1702
8:
B
Solution: First Term = 5760. Second term = 5760 /2 = 2880. Third Term = 2880/3 = 960. Fourth term = 960/4 = 240. Fifth term = 240/5 = 48. So,
Required term = 48/6 = 8.
9:
B
Solution: This is an alternating addition and subtraction series. Roman numbers alternate with Arabic numbers. In the Roman numeral pattern, each number decreases by 1. In the Arabic numeral pattern, each number increases by 1.
10:
B
Solution: This is a simple subtraction series in which a random number, 93, is interpolated as every third number. In the subtraction series, 10 is subtracted from each number to arrive at the next.
11:
D
Solution: In this simple addition with repetition series, each number in the series repeats itself, and then increases by 12 to arrive at the next number.
12:
D
Solution: This series alternates the addition of 4 with the subtraction of 3.
13:
B
Solution: In this series, the letters progress by 2, and the numbers increase by 2.
14:
A
Solution: Two series alternate here, with every third number following a different pattern. In the main series, 3 is added to each number to arrive at the next. In the alternating series, 5 is subtracted from each number to arrive at the next.
15:
A
Solution: By adding 300 to each term, we get the next term. 1060 is wrong term. It should be 1050.
16:
A
Solution: By subtracting 569, we get the next term. Required number, = 2845-569 = 2276.
17:
B
Solution: First term → 6 Second term → (6*2+1) = 13 Third term → (13*2+2) = 28 Fourth term → (28*2+3) = 59 Fifth term → (59*2+4) = 122 Sixth term → (122*2+5) = 249 So, the required term = 122.
18:
A
Solution: Above series contains two sub-series in it. 4, 10, 16, 22 8, 14, 20 Each of both term there is difference of 6 i.e. next term is 6 greater than previous term.
19:
C
Solution: First term → 9 Second term → (9 *2 -1) = 17 Third term → (17 *2 -1) = 33 Fourth term → (33 *2 -1) = 65 Fifth term → (65 *2 -1) = 129
20:
B
Solution: First term → 2 Second term → (2 *3 -3) = 3 Third term → (3 *3 -3) = 6 Fourth term → (6 *3 - 3) = 15 Fifth term → (15 *3 - 3) = 42 Sixth term → (42 *3 - 3) = 123
21:
D
Solution: The given pattern is, 2 nd term → 1*2+1 = 3 3 rd term → 3*3+1 = 10 4 th term → 10*2+1 = 21 5 th term → 21*3+1 = 64 6 th term → 64*2+1 = 129 7 th term → 129*3+1= 388 So, 7 th term 356 is wrong and must be replaced by 388 .
22:
B
Solution: Given pattern is, 2 nd term → 9*3 = 27 3 rd term → 27+4 = 31 4 th term → 31*5 = 155 5 th term → 155+6 = 161. 6 th term → 161*7 = 1127 Missing term → 1127+8 = 1135.
23:
B
Solution: The pattern is, 2 nd term → 2 +(5 *1 2 ) = 7 3 rd term → 7 +(5 *2 2 ) = 27 4 th term → 27 +(5 *4 2 ) = 107 5 th term → 107 +(5 *8 2 ) = 427 Missing term → 427 +(5 *16 2 ) = 1707
24:
A
Solution: Sunday to Monday = no gap Monday to Wednesday = One day gap. Wednesday to Saturday = Two days gap. Saturday to Wednesday = Three days gap. Wednesday to Monday = Four days gap. In the next term there must be five days and six days gap. So, Next term would be Sunday, Sunday.
25:
B
Solution: The correct sequence is + 1, + 3, + 5, + 7, + 9. So, 28 is wrong and must be replaced by (17 + 9) i.e., 26.
26:
D
Solution: The correct pattern is + 3, + 5, + 7, + 9, + 11. So, 33 is wrong and must be replaced by (24 + 11) i.e., 35.
27:
A
Solution: Clearly, each term of the series is the sum of the preceding two terms. Now, 8 + 13 = 21 and 13 + 21 = 34. So, the term 21 is missing.
28:
B
Solution: The correct sequence is + 4, + 6, + 8, + 10, ............ So, next term after 29 = 29 + 12 = 41. The term after 41 will then be (41 + 14) i.e., 55. ∴ 41 is missing.
29:
B
Solution: 1st term : 4 2nd term : 4 + 2 = 6 3rd term : 6 + 4 = 10 4th term : 10 + 6 = 16 5th term : 16 + 8 = 24 So, 6th term : 24 + 10 = 34
30:
C
Solution: According to the given question:
31:
A
Solution: 1st term : 3 2nd term : 3 + 2 = 5 3rd term : 5 + 4 = 9 4th term : 9 + 8 = 17 So, 5th term : 17 + 16 = 33
32:
B
Solution: 9 × 2 : 9 × 9 : : 9 × 5 : ? 18 : 81 : : 45 : 9 × 6 So. 9 × 6 will come in place of question mark.
33:
C
Solution: There are two series in the given question. 1st series: 1, 3, 5, 7 , 9 ... ( each next term are generated by adding 2) 2nd series: 0, 2, 6, 12, 20 ... ( each next term are generated by adding 2n [where n=1,2,3,4...])
34:
C
Solution: The series is as follows: 5 × 3 + 1 = 16 16 × 3 + 3 = 51 51 × 3 + 5 = 158 158 × 3 + 7= 481
35:
C
Solution: This is a simple multiplication series. Each number is 2 times greater than the previous number.
36:
B
Solution: Each number in the series is one more than twice the preceding number. So, the missing term = (15 x 2) + 1 = 31
37:
C
Solution: The pattern is +3,+5,+7,+9,............ So, missing term=(28+11)=39
38:
B
Solution: Each number in the series is 2 less than thrice the preceding number. So, missing number = (10 x 3) - 2 = 28
39:
C
Solution: The pattern is +2,+4,+2,+4, So, missing term = 25 + 4 = 29
40:
C
Solution: The pattern is x2+1,x2-1,x2+1,x2-1.x................... So, missing term =101x2+1=203
41:
A
Solution: The pattern is +6, +9, +12, +15............... So, missing term=21+12=33
42:
D
Solution: The pattern is x3+4, x4+4, x5+4,............... So, missing term=584x6+4=3508
43:
A
Solution: The pattern is +3, +4, +5, +6,........ So, missing term=9+5=14
44:
D
Solution: Each term of the series is obtained by multiplying the preceding term by 2. So, 96 is wrong and must be replaced by (64 × 2) i.e., 128.
45:
D
Solution: The correct pattern is + 1, - 2, + 3, - 4, + 5. So, 129 is wrong and must be replaced by (123 + 5) i.e., 128
46:
B
Solution: The correct pattern is + 1, + 4, + 9, + 16, + 25 i.e., + 1 2 , + 2 2 , + 3 2 , + 4 2 , + 5 2 . So, 22 is wrong and must be replaced by (16 + 4) i.e., 20.
47:
C
Solution: The correct pattern is - 20, - 25, - 30, ............ So, 0 is wrong and must be replaced by (30 - 35) i.e., - 5.
48:
C
Solution: The correct pattern is + 2, + 4, + 8, + 16, + 32, + 64 i,e., + 2, + 2 2 , + 2 3 , + 2 4 , + 2 5 , + 2 6 . So, 84 is wrong and must be replaced by (70 + 16) i.e., 86.
49:
C
Solution: The correct pattern is - 66, - 55, - 44, - 33, - 22, - 11. So, 202 is wrong and must be replaced by (259 - 55) i.e., 204.
50:
B
Solution: The correct pattern is × 1 + 1, × 2 + 2, × 3 + 3, × 4 + 4, .......... So, 32 is wrong and must be replaced by (10 × 3 + 3) i.e., 33.
