What should come in place of the question mark (?) in the given series?

779, 780, 784, 793, 809, ?

Given: 779, 780, 784, 793, 809, ?

Logic: Numbers are increasing perfect square of natural number from 1.

779 + 1 = 780

780 + 4 = 784

784 + 9 = 793

793 + 16 = 809

809 + 25 = 834

So, the missing term is 834.

Thus, correct option is (c).
