    Question

    Which of the following letter-number clusters will replace the question mark (?) in the given series to make it logically complete?
    PGE 18, TEI 26, XCM 34, BAQ 42, ?

    A.

    FCV 52

    B.

    FCU 52

    C.

    GYV 50

    D.

    FYU 50

    Correct option is D

    Given: PGE 18, TEI 26, XCM 34, BAQ 42, ?
    Logic: 1st letter + 4, 2nd letter - 2, 3rd letter + 4 and number + 8 place.
    For, 1st letter
    P + 4 = T, T + 4 = X, X + 4 = B, B + 4 = F
    For, 2nd letter
    G - 2 = E, E - 2 = C, C - 2 = A, A - 2 = Y
    For, 3rd letter
    E + 4 = I, I + 4 = M, M + 4 = Q, Q + 4 = U
    For, number
    18 + 8 = 26, 26 + 8 = 34, 34 + 8 = 42, 42 + 8 = 50
    So, the missing term is FYU 50.
    Thus, correct option is (d).
