    Question

    Which of the following numbers will replace the question mark (?) in the given series?
    62, 67, 74, 83, 94, 107, ?

    A.

    121

    B.

    120

    C.

    112

    D.

    122

    Correct option is D

    Series: 62, 67, 74, 83, 94, 107, ?
    The differences between consecutive terms:
    67−62=5
    74−67=7
    83−74=9
    94−83=11
    107−94=13
    Pattern of differences: increasing by +2 each time: 5, 7, 9, 11, 13.
    Determine the next difference should be 13+2=15.
    Adding 15 to the last term (107): 107+15=122.
