The missing number in the Series 114, 131, 165, 216, ?, 369

Correct Answer: 28

Explanation:

Here the given series 1, 6,  ?, 15, 45, 66, 91 follows a

Pattern in the series is, +5, +9, +13,...,.. +21, +25

So +4 is getting increased at every term addition.

Missing Number in the series will be 15+(9+4) = 15 + 13 = 28.

Correct Answer: 132

Explanation:

Given series is 

 

12        16         32          68         ?

 

Here it follows a pattern that,

 

12

 

12 + (2x2) = 16

 

16 + (4x4) = 32

 

32 + (6x6) = 68

 

68 + (8x8) = 132

Correct Answer: 635

Explanation:

Given Number series is 18     37     76     155     314     635

 

follows a pattern that, 

 

18

 

18 x 2 +1 = 37

 

37 x 2 +2 = 76

 

76 x 2 +3 = 155

 

155 x 2 +4 = 314

 

314 x 2 +5 = 633 not 635

 

 

 

Hence, the odd man is 635.

Correct Answer: 98

Explanation:

The given number series is 

3, 5, 8, 15, 28, 51, ?

Here the pattern it follows is

3

3 + 2 = 5 ( add prime number less than 3 i.e, 2)

5 + 3 = 8 (3 is prime number less than 5)

8 + 7 = 15 (7 is prime number less than 8)

15 + 13 = 28 (13 is prime number less than 15)

28 + 23 = 51 (23 is prime number less than 28)

51 + 47 = 98 (47 is prime number less than 51)

 

Hence, the next number in the given number series is 98.

Correct Answer: 45

Explanation:

Here given 

2, 3, 6, 15, ? , 157.5

2 x 1.5 = 3

3 x 2  = 6

6 x 2.5 = 15

15 x 3 = 45

45 x 3.5 = 157.5

Therefore, the missing number is 45

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: 181

Explanation:

Here the series follow the rule that

1 2 + 2 2 = 5

3 2 + 4 2 = 25

5 2 + 6 2 = 61

7 2 + 8 2 = 113

 

SO NEXT IS,  9 2 + 10 2 = 181

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: 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: 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.
