    Question

    What should come in place of the question mark (?) in the given series based on the English alphabetical order?
    PQT, UVY, ZAD, EFI, ?

    A.

    JKQ

    B.

    JKU

    C.

    JKN

    D.

    JKM

    Correct option is C

    Given: PQT, UVY, ZAD, EFI, ?
    Logic: Letters are increasing + 5 place.
    P + 5 = U, U + 5 = Z, Z + 5 = E, E + 5 = J
    Q + 5 = V, V + 5 = A, A + 5 = F, F + 5 = K
    T + 5 = Y, Y + 5 = D, D + 5 = I, I + 5 = N
    So, the missing term is JKN.
    Thus, correct option is (c).
