    Answer: (3) 33
    Explanation:-
    2 + 1 = 3,              3 + 1 x 2 = 5,        5 + 2 x 2 = 9,        9 + 2 x 4 = 17,     17 + 8 x 2 = 33

    Hence, the answer is (3) 33.

    Answer: (2) 162
    Explanation:-

    7 + 1 x 5 = 12,     12 + 2 x 5 = 22,   22 + 4 x 5 = 42,   42 + 8 x 5 = 82,                   82 + 16 x 5 = 162

    Hence, the answer is (2) 162.

    A + 2 = C,             C + 2 = E               and        A + 1 = B
    B + 2 = D,             D + 2 = F               and        B + 1 = C
    C + 2 = E,              E + 2 = G,             and        C + 1 = D
    D + 2 = F,              F + 2 = H               and        D + 1 = E

    Hence, the answer is (2) DFH.
