Question

Select the number from among the given options that can replace the question mark(?) in the following series.
1, 2, 5, 26, 677, ?

A.

3255

B.

45245

C.

24563

D.

458330

Correct option is D

Given: 1, 2, 5, 26, 677, ?
Logic: Each number is squared and 1 is added to get next number.
12+1=1+1=2
22+1=4+1=5
52+1=25+1=26
262+1=676+1=677
6772+1 = 458329+1 = 458330
So, missing number = 458330
Thus, option D is correct.
