    Question

    What should come in place of the question mark (?) in the given series?
    872 870 866 860 852 ?

    A.

    840

    B.

    842

    C.

    843

    D.

    841

    Correct option is B

    The given series is:
    872, 870, 866, 860, 852, ?
    Logic: The differences are decreasing by even numbers in a sequence: −2, −4, −6, −8
    872 → 870 (−2)
    870 → 866 (−4)
    866 → 860 (−6)
    860 → 852 (−8)
    Following this pattern, the next difference should be −10.
    Now calculate the next term:
    852 − 10 = 842
    Correct Answer: (B) 842
