# Find the Odd Number in the given Number Series?3, 6.5, 14, 29, 64, 136

 A) 14 B) 64 C) 29 D) 136

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 $\ne$29

30 x 2 + 4 = 64

64 x 2 + 8 = 136

Thus the wrong number in the series is 29

Q:

Find the odd man out in the following number series?

71, 88, 113, 150, 203, 277

 A) 277 B) 203 C) 150 D) 113

Explanation:

The given number series is

71      88       113       150       203          277

+17    +25       +37      +53        +74

+8      +12        +16       +21

+4          +4         +5

The series should be  71  88  112   150    203   276 i.e, the differences of the difference should be +4.

Hence, the odd man in the given series is 277.

Q:

Find the next number in the following number series?

11, 13, 30, 96, ?

 A) 264 B) 392 C) 412 D) 459

Explanation:

The given number series 11, 13, 30, 96, ? follows a pattern that,

11

11 x 1 + 2 = 13

13 x 2 + 4 = 30

30 x 3 + 6 = 96

96 x 4 + 8 = 392

Hence, the next number in the given series is 392.

Q:

Find the odd number out of the following number series?

2 4 8 11.5 18.25 28.375

 A) 18.25 B) 28.375 C) 11.5 D) 8

Explanation:

Given number series follows a pattern that,

2

2 x 1.5 + 1 = 4

4 x 1.5 + 1 = 7 (not equal to 8)

7 x 1.5 + 1 = 11.5

11.5 x 1.5 + 1 = 18.25

18.25 x 1.5 + 1 = 28.375

Q:

Find the odd man out in the following number series?

5, 4, 9, 32, 273

 A) 4 B) 9 C) 32 D) 273

Explanation:

The given number series follows 5, 4, 9, 32, 308 pattern that

5

5 x 1 - 1 = 4

4 x 3 - 3 = 9

9 x 5 - 5 = 40 (not equals to 32)

40 x 7 - 7 = 273

Hence, the odd man in the given number series is 32.

Q:

Find the next number in the sequence?

28, 16, 28, 76, 274

 A) 1233 B) 1243 C) 1256 D) 1276

Explanation:

Given number sequence is 28, 16, 28, 76, 274

Here the sequence follows a pattern that

28

28 x 0.5 + 2 = 14 + 2 = 16

16 x 1.5 + 4 = 24 + 4 = 28

28 x 2.5 + 6 = 70 + 6 = 76

76 x 3.5 + 8 = 266 + 8 = 274

274 x 4.5 + 10 = 1233 + 10 = 1243

Hence, the next number in the given number sequence is 1243.

Q:

Find the odd one out?

6, 3, 3, 4.5, 10

 A) 3 B) 4.5 C) 6 D) 10

Explanation:

Here the given number series is 6, 3, 3, 4.5, 10

The odd one in the given series is 10

The pattern it follows is

6

6 x 0.5 = 3

3 x  1  = 3

3 x 1.5 = 4.5

4.5 x 2 = 9

Hence, the odd number is 10.

Q:

Which is the next number in the sequence:

1, 3, 6, 11, 20, 37, ??

 A) 49 B) 56 C) 64 D) 70

Explanation:

Here the given series is 1, 3, 6, 11, 20, 37, ??,

and the logic behind the series is

1 x 2 + 1 = 3

3 x 2 + 0 = 6

6 x 2 + (-1) = 11

11 x 2 + (-2) = 20

20 x 2 + (-3) = 37

37 x 2 + (-4) = 70

Hence, the next number in the given series is 70.

Q:

What is the next number in the following number series

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

 A) 98 B) 102 C) 87 D) 79

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.
