In the following question, select the odd letters from the given alternatives.

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: 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: 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: 502

Explanation:

The given series is 12, 48, 168, 502, 1260

12

12 x 4 = 48

48 x 3.5 = 168

168 x 3 = 504

504 x 2.5 = 1260

 

Hence, the odd man out in the given series is 502.

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: 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.

Correct Answer: 80

Explanation:

Next number of the sequence 1, 4, 12, 32,...

1 = 2 x  2 0

4 = 2 x  2 1

12 = 3 x  2 2

32 = 4 x  2 3

80 = 5 x  2 4.

Correct Answer: 35

Explanation:

Here the given number series is 0, 3, 8, 15, 24, ?

The next number in the given series can be found such a way that the number series follows a pattern,

$$\begin{gathered} 2 2 - 4 = 0 \\ 3 2 - 6 = 3 \\ 4 2 - 8 = 8 \\ 5 2 - 10 = 15 \\ 6 2 - 12 = 24 \\ 7 2 - 14 = 35 \\ Hence , the next number in the iven series is 35 . \end{gathered}$$

Correct Answer: -1

Explanation:

3, 7, 6, 5, 9, 3, 12, 1, 15, ... has two different series

1) 3, 6, 9, 12, 15.....

2) 7, 5, 3, 1, .....

-1 is the next number.

Correct Answer: 65

Explanation:

The given number series is 50, 51, 47, 56, 40, ?

 

$$\begin{gathered} 50 \\ 50 + 1 2 = 51 \\ 51 - 2 2 = 47 \\ 47 + 3 2 = 56 \\ 56 - 4 2 = 40 \\ 40 + 5 2 = 65 \end{gathered}$$

 

Hence, the next number in the given number series is 65.
