    Question

    Which of the following letter-number clusters will replace the question mark (?) in the given series to make it logically complete?
    NTZ 14, KQW 23, HNT 32, EKQ 41, BHN 50, ?​​

    A.

    YEK 58

    B.

    ZEK 59

    C.

    YKK 59

    D.

    YEK 59

    Correct option is D

    ​​Given Series:
    NTZ 14, KQW 23, HNT 32, EKQ 41, BHN 50, ?
    Logic: Each letter is decreasing by 3 places and number is increasing by +9
    First Letter;
    N - 3 → K, K - 3 → H, H - 3 → E, E - 3 → B, B - 3 → Y
    So, the next first letter is Y.
    Second Letter
    T - 3 → Q, Q - 3 → N, N - 3 → K, K - 3 → H, H - 3 → E
    So, the next second letter is E.
    Third Letter
    Z - 3 → W, W - 3 → T, T - 3 → Q, Q - 3 → N, N - 3 → K
    So, the next third letter is K.
    Number Pattern
    14 + 9 = 23
    23 + 9 = 32
    32 + 9 = 41
    41 + 9 = 50
    50 + 9 = 59
    So, the next number is 59.
    The missing letter-number cluster is YEK 59
    Thus, correct  Option is (D) YEK 59
