Question

Select the number that can replace the question mark (?) in the following series.

50, 49, 53, 44, 60, 35, ?

1. 71
2. 117
3. 70
4. 104

Answer 1

Correct Answer - Option 1 : 71

Given,

50, 49, 53, 44, 60, 35, ?

The pattern followed here is,

50 - 1 (1²) = 49

49 + 4 (22) = 53

53 - 9 (32) = 44

44 + 16 (42) = 60

60 - 25 (52) = 35

35 + 36 (62) = 71

Hence, the correct answer is 71.
