LS-002

Find the next letter: M – Q – U – Y – C – ?

Rule: Shift forward by 4 each time.

So the next letter is G.

• Picking the first pattern you see without checking it against all rows/columns.
• Ignoring the simplest rule (counts, rotations, alternations) and jumping to a complex story.
• Not testing your rule on the middle row/column (where many puzzles “break” bad rules).
