    Question

    Which of the following numbers will replace the question mark (?) in the given number series?
    29, 30, 34, 43, 59, ?

    A.

    84

    B.

    79

    C.

    86

    D.

    32

    Correct option is A

    Given: 29, 30, 34, 43, 59, ?
    Logic: Adding the square of consecutive numbers 1, 2, 3, 4, 5, in this series; 
    29 + 12=  30,
    30 + 22 = 34,
    34 + 32 = 43,
    43 + 42 = 59, 
    Next number will be;
    59 + 52= 84.
    Thus, the correct answer is (a) 84.
