6  18  38  66 ?
A. 74
B. 36
C. 84
D. 82
E. 102

E. 102

The given series follows the pattern as
2 + 22 = 2 + 4 = 6
2 + 42 = 2 + 16 = 18
2 + 62 = 2 + 36 = 38
2 + 82 = 2 + 64 = 66
2 + 102 = 2 + 100 = 102
So, the required number in the series is 102.

2.What will come in place of the question mark (?) in the following number series?
6  9  17  32  56  ?
A. 63
B. 91
C. 132
D. 85
E. None of these

B. 91

The given series follows the pattern as
6
6 + 22 – 1 = 9
9 + 32 – 1 = 17
17 + 42 – 1 = 32
32 + 52 – 1 = 56
56 + 62 – 1 = 91
So, the required number in the series is 91.

3.Find the missing number in the following series-
0  26  124  342  728  ?
A. 999
B. 735
C. 835
D. 642
E. None of these

E. None of these

The given series is in the following pattern:
13 – 1 = 0
33 – 1 = 26
53 – 1 = 124
73 – 1 = 342
93 – 1 = 728
113 – 1 = 1330

4.Find the missing number in the following series-
1   2   4   5   10   11   22   ?
A. 27
B. 24
C. 16
D. 25
E. None of these

E. None of these

The given series is in the following Pattern:
1
1 + 1 = 2
2 × 2 = 4
4 + 1 = 5
5 × 2 = 10
10 + 1 = 11
11 × 2 = 22
22 + 1 = 23
So, the missing term is 23.

5.Find the missing number in the following series-
520, 516, 511, 495, 471, ?
A. 448
B. 452
C. 399
D. 336
E. 442

C. 399

Given series is based on the following pattern.
520 – 22 = 516
520 – 32 = 511
520 – 52 = 495
520 – 72 = 471
2, 3, 5 and 7 are prime numbers and next prime number is 11.
∴ Missing number is 520 – 112 = 399

6.What will come in the place of question mark (?) in the following number series?
6,  42,   ?,  1260,  5040,  15120,  30240
A. 978
B. 654
C. 345
D. 252
E. 288

D. 252

The pattern of the given number series is as following:
→ 6,
→ 6 × 7 = 42,
→ 42 × 6 = 252,
→ 252 × 5 = 1260,
→ 1260 × 4 = 5040,
→ 5040 × 3 = 15120,
→ 15120 × 2 = 30240
Hence, the required number in place of question mark in the given number series would be 252

7.What will come in the place of question mark (?) in the following number series?
62,  87,  187,  412,  812,  ?
A. 1178
B. 1437
C. 2437
D. 1735
E. 3478

B. 1437

The pattern of the given number series is as following:
→ 62,
→ 62 + 52 = 87,
→ 87 + 102 = 187,
→ 187 + 152 = 412,
→ 412 + 202 = 812,
→ 812 + 252 = 1437
Hence, the required number in place of question mark in the given number series would be 1437

8.Find the wrong term in the following number series-
16,  14,  24,  66,  250, 1270
A. 66
B. 24
C. 14
D. 1270
E. 250

E. 250

The pattern of the given number series is as following:
→ 16,
→ 16 × 1 – 2 = 14,
→ 14 × 2 – 4 = 24,
→ 24 × 3 – 6 = 66,
→ 66 × 4 – 8 = 256,
→ 256 × 5 – 10 = 1270
Hence, the required wrong term in the given number series is 250, therefore option 5 is correct

9.Find the wrong term in the following number series-

D. 37
E. 121.5

D. 37

The pattern of the given number series is as following:
→ 16,
→ 16 × 3 ÷ 2 = 24,
→ 24 × 3 ÷ 2 = 36,
→ 36 × 3 ÷ 2 = 54,
→ 54 × 3 ÷ 2 = 81,
→ 81 × 3 ÷ 2 = 121.5
Hence, the required wrong term in the given number series is 37
