What is the next number in the given Number Series? 5, 24, 94, 279, ?

Correct Answer: 22

Explanation:

In the given series 1 4 9 16 22 36

1 = 1 x 1 

4 = 2 x 2

9 = 3 x 3

16 = 4 x 4

25 = 5 x 5 (Not 22)

36 = 6 x 6

 

Hence, the odd man in the series is 22.

Correct Answer: 69

Explanation:

The given number series is 152, 124, 96, 69, 40

152

152 - 28 = 124

124 - 28 = 96

96 - 28 = 68 (not 69)

68 - 28 = 40

 

Hence, the odd man in the given number series is 69.

Correct Answer: 144

Explanation:

Here the series follows,

194

194 - (1x1 - 1) = 194

194 - (2x2 - 1) = 191

191 - (3x3 - 1) = 183

183 - (4x4 - 1) = 168

168 - (5x5 - 1) = 144

Correct Answer: 328

Explanation:

2.5 × 1 + 1 = 3.5

3.5 × 2 + 2 = 9

9 × 4 + 4 = 40

40 × 8 + 8 = 328

Correct Answer: 16

Explanation:

The given number series is 8, 16, 20, 36, 68

8

8 x 2 - 4 = 12 (NOT 16)

12 x 2 - 4 = 20

20 x 2 - 4 = 36

36 x 2 - 4 = 68

 

Hence, the odd man in the given series is 16.

Correct Answer: 121

Explanation:

343 = 7 3,  1331 =  11 3 , 2197 = 13 3, 121 =  11 2

 

343, 1331, 2197 are perfect cubes, but not 121.

Correct Answer: 165

Explanation:

The terms of the series are products of two consecutive prime numbers i.e.

(2 x 3), (3 x 5), (5 x 7), (7 x 11),.....

So, 165 is wrong and must be replaced by (11 x 13) i.e. 143.

Correct Answer: 150

Explanation:

The numbers are 7 x 8, 8 x 9, 9 x 10, 10 x 11, 11 x 12, 12 x 13.

So, 150 is wrong.

Correct Answer: 64

Explanation:

The given number series follows a pattern that

196, 169, 144, 121, 100, 81, ?

    -27  -25   -23   -21  -19  -17

 

=> 81 - 17 = 64

Therefore, the series is 196, 169, 144, 121, 100, 81, 64.
