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.
