    Answer:  (1) 46

    Explanation:-
    1, 6, 13, 22, 33, ?

    1 + 5 = 6,
    6 + (5 + 2)  = 6 + 7 = 13,
    13 + (7 + 2) = 13 + 9 = 22,
    22  + (9 + 2)  = 22 + 11 = 33,
    Similarly,
    33 + (11 + 2) = 33 + 13  =  46.

    Then,  the missing number is 46.

    Hence, the answer is (1) 46.
