In the following question, a series is given with one term missing. Choose the correct term to complete the sequence.
PMT, OOS, NQR, MSQ, ?
Show answer & explanation
Correct answer: B
Explanation
The pattern followed by the letters in each position is:
• First letter: P (−1) → O (−1) → N (−1) → M (−1) → L
• Second letter: M (+2) → O (+2) → Q (+2) → S (+2) → U
• Third letter: T (−1) → S (−1) → R (−1) → Q (−1) → P
Thus, the missing term is LUP.
