Question

Which of the following letter-clusters will replace the question mark (?) in the given series to make it logically complete?

MAN 7, PDQ 16, SGT 25, VJW 34, ?

A.

ULZ 40


B.

YMZ 43


C.

YNZ 43


D.

ZLU 36

Correct option is B

Given: MAN 7, PDQ 16, SGT 25, VJW 34,
The numbers in the series are 7, 16, 25, 34, with a difference of +9 between consecutive terms:
7+9=16
16+9=25
25+9=34
34+9=43
Thus, the next number is 43.
Analyze the letters
We observe each letter in the clusters MAN, PDQ, SGT, VJW:
First letter progression (M, P, S, V):
M → P → S → V, each moves forward by +3 in the alphabet.
Next letter: V+3= Y.
Second letter progression (A, D, G, J):
A → D → G → J, each moves forward by +3 in the alphabet.
Next letter: J+3=M.
Third letter progression (N, Q, T, W):
N → Q → T → W, each moves forward by +3 in the alphabet.
Next letter: W+3=Z.
Combine results
The next letter-cluster is YMZ, and the corresponding number is 43.
Final Answer: (B) YMZ 43
