Correct Answer: 14
Explanation:
Here the given series is 128, 32, 14, 2.66, 0.88
128 / 4 = 32
32 / 3 = 10.666
10.666 / 4 = 2.666
2.666 / 3 = 0.888
Hence, the odd man in the given number series is 14.
Correct Answer: 63
Explanation:
Here the series follows the pattern that, product of succesive prime numbers i.e,
2 × 3 = 6
3 × 5 = 15
5 × 7 = 35
7 × 11 = 77
11 × 13 = 143
13 × 17 = 221
17 × 19 = 323
So here in place of 77 the number 63 is written.
So the wrong number is 63.
Correct Answer: 225
Explanation:
The series follows the following pattern
5 X 5 ? 5 = 20
20 X 4 ? 4 = 76
76 X 3 ? 3 = 225
225 X 2 ? 2 = 448
Hence, the term 225 denoted by (d) completes the series
Correct Answer: 181
Explanation:
Here the series follow the rule that
SO NEXT IS,
Correct Answer: 92
Explanation:
The given series of numbers follow the rule that,
2880/6 = 480
480/5 = 96
96/4 = 24
24/3 = 8
8/2 = 4
4/1 = 4
But 92 is not in the rule. It is the wrong number in the given series.
Correct Answer: 18.5
Explanation:
The given series pattern follows
17 9 10 18.5 35 90
× 0.5 + 0.5, × 1 + 1, × 1.5 + 1.5, × 2 + 2, × 2.5 + 2.5
So here
17x0.5 + 0.5 = 9
9x1 + 1 = 10
10x1.5 + 1.5 = 16.5
16.5x2 + 2 = 35
35x2.5 + 2.5 = 90
Here the odd man in the given series is 18.5
Correct Answer: 75
Explanation:
Here in the given series, it follows a pattern that
77 + 2 = 79
79 - 3 = 76
76 + 5 = 81
81 - 7 = 74
74 + 11 = 85
Consecutive adding and subtracting of prime numbers.
So the wrong number in the given series is 75.
Correct Answer: 29
Explanation:
The Given number series 3, 6.5, 14, 29, 64, 136 follows a pattern that
3
3 x 2 + 0.5 = 6.5
6.5 x 2 + 1 = 14
14 x 2 + 2 = 30 29
30 x 2 + 4 = 64
64 x 2 + 8 = 136
Thus the wrong number in the series is 29
Correct Answer: 67
Explanation:
Here the given number series is 3, 14, 36, 67, 113, 168
It follows a pattern that
3
3 + 1 x 11 = 3 + 11 = 14
14 + 2 x 11 = 14 + 22 = 36
36 + 3 x 11 = 36 + 33 = 69
69 + 4 x 11 = 69 + 44 = 113
113 + 5 x 11 = 113 + 55 = 168
Hence, the wrong number is 67.
Correct Answer: 91.12
Explanation:
Given number series is 12 9 13.5 30.3 ? 341.7
Here the pattern followed by the series is
12
12 x 0.75 = 9
9 x 1.5 = 13.5
13.5 x 2.25 = 30.3
30.37 x 3 = 91.12
91.12 x 3.75 = 341.71
Hence, the missing number in the sequence is 91.12.
