    A. Answer: (3) 138
    Explanation:-
    7 + 8 = 15,            15 + 2 x 8 + 1 = 15 + 17 = 32,                         32 + 2 x 17 + 1 = 32 + 35 = 67,                       67 + 2 x 35 + 1 =  67 + 71 = 138.
    Thus, the next number is 138.

    B. Answer: 
    Explanation:-
    7 + 2 = 9,             9 + 2 x 2 = 9 + 4 = 13,                   13 + 2 x 4 = 13 + 8 = 21,               21 + 2 x 8 = 21 + 16 = 37,                 37 + 2 x 16 = 37 + 32 = 69.
    Thus, the answer is (2) 69.

    C. Answer: (1) Q8
    Explanation:-
    A + 4 = E     and 103 = 10 x 10 x 10 = 1000
    E + 4 = I       and  10 – 2 = 8 = 83 = 8 x 8 x 8 = 512
    I + 4 = M      and  8 – 2 = 6  =  63 = 6 x 6 x 6 = 216
    M + 4 = Q     and  6 – 2 = 4 = 43 = 4 x 4 x 4 = 64
       and 4 – 2 = 2 = 23 = 2 x 2 x 2 = 8
    Thus, the answer is Q8.

    D. Answer: (4) 8
    Explanation:-
    22/ 2 = 11,                    30/ 3 = 10,                      36/ 4 = 9,            40/5 = 8.
    Thus, the answer is (4) 8.

    E. Answer:
    Explanation:-
    1 + 1= 2     and A is opposite of Z,                       2 + 1 = 3       and      B is opposite of Y,
    3 + 1 = 4     and C is opposite of X,             
    Thus, the answer is (1) X.
