The idea
A constant letter gap is the simplest pattern. Count carefully — miscounting by one is the only real risk.
Shortcut. Skip two letters each time: after K skip L and M to land on N (position 14, one short of the O = 15 landmark).
Common trap. M — counting K itself as the first of the three steps (K, L, M); K + 3 means three moves on from K: L, M, N.
