Find the odd man out? 12, 48, 168, 502, 1260

Correct Answer: 122

Explanation:

Here the given series is 123 112 133 112 143

It follows a pattern that,

123

123 - 11 = 112

112 + 21 = 133

133 - 31 = 102 (not 122)

102 + 41 = 143

 

Hence, the odd man in the given number sequence is 122 instead of 102.

Correct Answer: 12

Explanation:

The given series follows a pattern that,

 

$$\begin{gathered} 4 + 3 2 = 4 + 9 = 13 \\ 13 + 5 2 = 13 + 25 = 38 \\ 38 + 7 2 = 38 + 49 = 87 \\ 87 + 9 2 = 87 + 81 = 198 \end{gathered}$$ 

 

Hence, the odd man in the given number series is 12.

Correct Answer: 135

Explanation:

The given number series is 6, 6, 9, 18, 45, ?

Here the series follows a pattern that,

6 

6 x 1 = 6

6 x 1.5 = 9

9 x 2 = 18

18 x 2.5 = 45

45 x 3 = 135

 

Hence, the next number in the given number series is 135.

Correct Answer: 90

Explanation:

The given number series follows a pattern that,

56

56 + 8 = 64

64 - 16 = 48

48 + 32 = 80 (Not equal to 90)

80 - 64 = 16

16 + 128 = 144 

 

Hence, the odd number in the given number series is 90.

Correct Answer: 420

Explanation:

The given number series 410, 409, 413, 404, ? , follows a pattern that 

410

$$\begin{gathered} 410 - 1 3 = 409 \\ 409 + 2 2 = 413 \\ 413 - 3 3 = 404 \\ 404 + 4 2 = 420 \end{gathered}$$

 

Hence, the next number in the given series is 420.

Correct Answer: 12.4

Explanation:

The given series 24.3, 23.1, 20.7, 17.1, 12.4 follows a pattern that

24.3

24.3 - 1.2 = 23.1

23.1 - 2.4 = 20.7

20.7 - 3.6 = 17.1

17.1 - 4.8 = 12.3 not 12.4

 

Hence, the odd man or odd number in the given series is 12.4

Correct Answer: 978

Explanation:

The given series is 1000, 1012, 988, 1024, 978

1000

1000 + 12 = 1012

1012 - 24 = 988

988 + 36 = 1024

1024 - 48 = 976 (Not 978)

Correct Answer: 14

Explanation:

The given series is 8, 14, 24, 60, 180

8

8 x 1.5 = 12 (NOT 14)

12 x 2 = 24

24 x 2.5 = 60

60 x 3 = 180

 

Hence, the odd man in the given series is 12.

Correct Answer: ET

Correct Answer: 186

Explanation:

The given number series is 3  24  186  1008  5040  20160

Here  the given series follows a pattern that,

3

3 x 8 = 24

24 x 7 = 168 not 186

168 x 6 = 1008

1008 x 5 =  5040

5040 x 4 = 20160

 

Hence the Odd One in the number series is 186.
