How to play Number Sequence

Rules

1. Read the numbers from left to right and fill every gap.
2. Some lines interleave two patterns.
3. A copied-error puzzle tells you that exactly one displayed number is wrong.

How to answer

1. Enter the missing values. In a copied-error puzzle, tap a suspect number to mark it while you work.
2. Choose Submit number or Submit numbers. Suspect marks are notes and are not submitted.
3. Your draft is saved. Undo reverses entries and suspect marks.

Solving tips

• Compare gaps and ratios, then try every other position.
• Check that your rule explains all the terms except any stated copied error.
