Question

​What should come in place of the question mark (?) in the given series?
110, 221, 443, 887, 1775, ?

A.

2051

B.

2751

C.

3551

D.

3051

Correct option is C

Given: 110, 221, 443, 887, 1775, ?
Logic: Previous Term × 2 + 1 = Next Term
110 × 2 + 1 = 220 + 1 = 221
221 × 2 + 1 = 442 + 1 = 443
443 × 2 + 1 = 886 + 1 = 887
887 × 2 + 1 = 1774 + 1 = 1775
1775 × 2 + 1 = 3550 +1 = 3551
So, ? = 3551
Thus, the correct option is (c) 3551.
