    Question

    What should come in place of the question mark (?) in the given series?
    108, 122, 139, 159, 182, 208, ?

    A.

    222

    B.

    237

    C.

    229

    D.

    248

    Correct option is B

    ​​Series:
    108, 122, 139, 159, 182, 208, ?
    Logic: Differences are increasing by +3 each time:​
    122 − 108 = 14
    139 − 122 = 17
    159 − 139 = 20
    182 − 159 = 23
    208 − 182 = 26
    next = 29
    So,
    208 + 29 = 237
    Thus, correct option is (B) 237.
