Which number will replace the question mark (?) in the following series? `7, 14, 33, 70, 131,` ?

Options

A. 190
B. 218
C. 131
D. 222

Answer

D

Explanation

Difference between consecutive numbers have been taken
14−7 = 7, 33−14 = 19, 70−33 = 37 "and" 131−70 = 61.
again, these 7,19,37,61 are also in a series in following manner.
19−7 = 12, 37−19 = 18, 61−37 = 24.
So, next number will be added by 30 to 61(which will be 91). And it will be added to 131. So, required number is `=131+61+30+222`.
option D is correct.
