Find the next number in the number series? 6, 6, 9, 18, 45, ?

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: 56

Explanation:

The given number series follows a pattern that,

9

9 x 0.5 + 0.5 = 5

5 x 1 + 1 = 6

6 x 2 + 2 = 14

14 x 4 + 4 = 60 (not equals to 56)

60 x 8 + 8 = 488.

 

Hence, the odd one in the given number series is 56.

Correct Answer: 32

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.

Correct Answer: 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.

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: 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: 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: 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)
