What should come in place of the question mark '?' in the following number series?58, 67, 95, 160, 286, ?1. 5932. 6033. 6134. 5635. None of these

Answer» Correct Answer - Option 5 : None of these

The series follows the following pattern:

58

58 + (23+ 1) = 67

67 + (33+ 1) = 95

95 + (43+ 1) = 160

160 + (53+ 1) = 286

286 + (63+ 1) = 503

∴ The missingterm in the series is 503.

Logic: Cube of number + 1 (Constant)

In the following number series, a wrong number is given. Find out the wrong number.24, 13, 14, 22, 45, 112.51. 112.52. 453. 144. 135. 24

Answer» Correct Answer - Option 1 : 112.5

Given:

24, 13, 14, 22, 45, 112.5

Calculation:

The logic that follows here is:

24× 0.5 + 1 = 12 + 1 = 13

13× 1 + 1 = 13 + 1 = 14

14× 1.5 + 1 = 21 + 1 = 22

22× 2 + 1 = 44 + 1 = 45

45× 2.5 + 1 = 112.5 + 1 = 113.5≠ 112.5

There should be 113.5 instead of 112.5.

∴ 112.5 is the wrong term.

What should come in place of question mark ‘?’ in the following number series?10, 30, 69, 132, 227, ?1. 2562. 3563. 1564. 4565. 336

Answer» Correct Answer - Option 2 : 356

Calculation:

Considering the above series,

10, 30, 69, 132, 227, ?

The logic of the series can be explained as,

(2)3 + 2 = 10

(3)3 + 3 = 30

(4)3 + 5 = 69

(5)3 + 7 = 132

(6)3 + 11 = 227

By observing the pattern, we can write

(7)3 + 13 = 356

⇒ ? = 356

∴ The value of ? is 356.
