Letter rows

Level 7 · for questions like “A, C, E, G, ?”

💡 The idea

Letters are numbers in disguise: A = 1, B = 2 … Z = 26. A letter row is a number row.

🪜 The steps

1. Turn each letter into its number.
2. Look at the jumps between them.
3. Is the jump always the same, or does it grow?
4. Turn the next number back into a letter.

⚠️ Watch out

• Handy anchors: E = 5, J = 10, O = 15, T = 20.
• Growing jumps (+1, +2, +3…) are common.

🎯 Try these

1. B, E, H, K, ?
2. A, B, D, G, K, ?
