    Question

    Which of the following numbers will replace the question mark (?) in the given series?
    3, 11, 20, 28, 37, ?

    A.

    45

    B.

    55

    C.

    54

    D.

    44

    Correct option is A

    Given: 3, 11, 20, 28, 37, ?
    Logic: The pattern alternates between adding and 9 alternatively.
    11 - 3 = 8 
    20 - 11 = 9
    28 - 20 = 8
    37 - 28 = 9
    the next term:
    ? - 37  = 8 
    ? = 37 + 8 
    ? = 45 
    Thus, the correct answer is (a) 45.
