A series is given with one term missing. Select the correct alternative from the given ones that will complete the series. PQMN, STPQ, VWST, YZVW,?

Correct option is A

Given series PQMN, STPQ, VWST, YZVW,?
The alphabet table is given with its place value:

Pattern: Each letter moves +3 steps forward in the alphabet.
1. First Pair Analysis (PQ → ST → VW → YZ):
PQ+3=ST

P +3=S and Q+3= T

ST +3= VW
S+3=V and T+3= W

VW +3=YZ
V +3= Y and W +3=Z
The first pair follows a consistent pattern where each letter moves +3 steps forward in the alphabet.
2. Second Pair Analysis (MN → PQ → ST → VW):
MN +3= PQ

M+3= P and N+3= Q
PQ +3= ST

P+3=S and Q+3=T
ST+3=VW

S +3=V and T+3=W
The second pair also follows a consistent pattern where each letter moves +3 steps forward in the alphabet.
Determining the Missing Term:
Following the pattern identified above, each letter in the next term must also move +3 steps forward:
YZ+3=BC

Y +3=B and Z +3= C (Considering the cycle in the alphabet)

VW +3= YZ

V+3= Y and W+3=Z
The next pair, similarly, shifts each letter forward by +3 steps.
So, the missing term is “ BCYZ”.
Hence, option(a) is the correct answer.
