    Question

    What should come in place of the question mark (?) in the given series?
    823, 822, 820, 817, 813, ?

    A.

    807

    B.

    810

    C.

    808

    D.

    809

    Correct option is C

    Given: 823, 822, 820, 817, 813, ?
    Logic: The difference between consecutive numbers increases by 1, starting from 1 (eg. -1,-2, -3, -4, -5)
    823 - 1 = 822
    822 - 2 = 820
    820 - 3 = 817
    817 - 4 = 813
    813 - 5 = 808
    So, the next number in the series is 808.
    Thus, the correct option is (c) 808.
