Step 1: Analyzing the pattern
Each of the terms in the series is formed by three consecutive letters in the alphabet, with a consistent pattern:
- First term: QPO (Q is followed by P and O).
- Second term: SRQ (S is followed by R and Q).
- Third term: UTS (U is followed by T and S).
- Fourth term: WVU (W is followed by V and U).
By following this consistent pattern, the next term will have letters that are consecutive in reverse order.
Step 2: Find the missing term
The next sequence follows the reverse pattern. After W, we have X, followed by Y and Z.
The missing term is therefore YXW.
Step 3: Final Answer
The correct answer is (b) YXW.
Final Answer: The correct answer is (b) YXW.
