Question

Find the missing number in the following series.
35, 46, 59, 74, (….), 110

A.

81

B.

83

C.

91

D.

87

Correct option is C

This is an increasing sequence with a pattern of adding increasing differences between consecutive terms.
· First, calculate the differences between successive numbers:
· 46 - 35 = 11
· 59 - 46 = 13
· 74 - 59 = 15
The differences are increasing by 2 each time. So, the next difference should be 17.
· Add this difference to 74:
· 74 + 17 = 91
Thus, the missing number is 91. Therefore, the next number will be 110 as given in the series.
Correct answer: (c) 91.
