    Question

    Select the number from among the given options that can replace the question mark (?)in the following series.
    10, 14, 34, 62, 130, ?

    A.

    250

    B.

    259

    C.

    254

    D.

    252

    Correct option is C

    Given series: 10, 14, 34, 62, 130, ?
    Logic:  (number × 2) − 6 & + 6 alternatively
    10 × 2 = 20, then 20 − 6 = 14
    14 × 2 = 28, then 28 + 6 =  34
    34 × 2 = 68, then 68 − 6 = 62
    62 × 2 = 124, then 124 + 6 = 130
    130 × 2 = 260, then 260 − 6 = 254
    So, the missing term is 254.
    Thus, the correct option is (c).
