Concept:Each letter in the first pair is shifted forward by a fixed number of positions to get the corresponding letter in the second pair.Explanation: K (11th letter) becomes L (12th) – add 1. P (16th letter) becomes W (23rd) – add 7. Apply the same shifts to M and Q. M (13th) + 1 = N (14th). Q (17th) + 7 = X (24th). So the missing term is NX.
