Question

What should come in place of the question mark (?) in the given series?
801, 800, 797, 792, 785, ?

A.

773

B.

775

C.

776

D.

774

Correct option is C

Given:
801, 800, 797, 792, 785, ?
Logic: The difference between consecutive terms is increasing by 2 each time: 1, 3, 5, 7, 9.
801 - 1 = 800
800 - 3 = 797
797 - 5 = 792
792 - 7 = 785
Similarly,
785 - 9 = 776
Thus, the correct option is (c).
