    Question

    Which of the following terms will replace the question mark (?) in the given series to make it logically complete?
    VZL15, TXJ18, RVH21, PTF24, ?

    A.

    LMN27

    B.

    DRN27

    C.

    NRD27

    D.

    RND27

    Correct option is C

    Given: VZL15, TXJ18, RVH21, PTF24, ?
    Logic: all letters decrease by -2 and number increases by +3
    Explanation:
    First letter: V-2=T, T-2=R, R-2=P, So, P-2=N
    Second letter: Z-2=X, X-2=V, V-2=T, So, T-2=R
    Third letter: L-2=J, J-2=H, H-2=F, So, F-2=D
    Number: 15+3=18, 18+3=21, 21+3=24, So, 24+3=27
    So, ? is replaced by NRD27
    Thus, Option C is the correct answer.
