    Question

    Find the missing term in the following number series.
    2, 6, 12, 20,______, 42

    A.

    36

    B.

    32

    C.

    34

    D.

    30

    Correct option is D

    Given: 
    2, 6, 12, 20,______, 42
    Logic: The differences between consecutive numbers are increasing by 2:
    2 + 4 = 6
    6 + 6 = 12
    12 + 8 = 20
    20 + 10 = 30
    30 + 12 = 42
    Therefore, the missing number is 30.
    Thus, correct option is (d).
