Question

What should come in place of the question mark (?) in the given series?
180, 131, 90, 57, 32, (?)

A.

22

B.

20

C.

17

D.

15

Correct option is D

Given: 180, 131, 90, 57, 32, (?)
Logic: ​The given series follows the pattern of double difference. Subtract 8 from the difference between the consecutive terms to get the next term in the series.​​
180 - 49 = 131
131 - (49 - 8) = 131 - 41 = 90
90 - (41 - 8) = 90 - 33 = 57
57 - (33 - 8) = 57 - 25 = 32
Similarly, 32 - (25 - 8) = 32 - 17 = 15
So, 15 is the missing term in the series.
Thus, the correct answer is (d).
