Question

Which of the following numbers will replace the question mark (?) in the given series?
8, 9, 64, 25, 216, ?

A.

125

B.

72

C.

49

D.

81

Correct option is C

Given,
8, 9, 64, 25, 216, ?
Logic: The logic follows an alternating pattern of cube and square.
8 = 2³, 9 = 3², 64 = 4³, 25 = 5², 216 = 6³
So, the last number follows the square pattern: 72 = 49
The missing number should be: 49
Thus, the correct option is: (c)
