Find the odd man out from the given series? 8, 18, 56, 232, 1165

Correct Answer: 254

Explanation:

The given series 16, 254, 1296, 4096, 10000 follows a pattern that

 

2 4 , 4 4 , 6 4 , 8 4 , 10 4 , . . .

Hence, the odd man in the series is 4 x 4 x 4 x 4 = 256 not 254.

Correct Answer: 121

Explanation:

Given number series is 61, 66, 83, 121, 185

Here the given series follows a pattern that,

 

$$\begin{gathered} 61 \\ 61 + 2 2 + 1 = 66 \\ 66 + 4 2 + 1 = 83 \\ 83 + 6 2 + 1 = 120 ( not 121 ) \\ 120 + 8 2 + 1 = 185 \end{gathered}$$

 

 

Hence, the odd man in the given series is 121.

Correct Answer: 7.5

Explanation:

The given number series follows a pattern that

11

11 - 5.5 = 5.5

5.5 + 4.5 = 10

10 - 3.5 = 6.5

6.5 + 2.5 = 9

9 - 1.5 = 7.5

 

Hence, the next number in the given number series is 7.5.

Correct Answer: 278.5

Explanation:

The given number series is 35, 36, 55, 111, ?

35

35 x 1 + 1 = 36

36 x 1.5 + 1 = 55

55 x 2 + 1 = 111

111 x 2.5 + 1 = 278.5

 

Hence, the next number in the given number series is 278.5.

Correct Answer: 277

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.

Correct Answer: 40

Explanation:

The given number series is 180, 90, 60, 40, 36

It follows a pattern that,

180 x 1/2 = 90

90 x 2/3  = 60

60 x 3/4  = 45 (NOT 40)

45 x 4/5  = 36

 

Hence, the wrong number in the given series is 40.

Correct Answer: 80

Explanation:

The given number series is 3, 11, 80, 291, 803

$$\begin{gathered} 3 \\ 3 + 2 3 = 3 + 8 = 11 \\ 11 + 4 3 = 11 + 64 = 75 ( not 80 ) \\ 75 + 6 3 = 75 + 216 = 291 \\ 291 + 8 3 = 291 + 512 = 803 \end{gathered}$$
