Sequence challenges
These are individual rows, each with its own answer. They are here so you can practise the search. They are not a Sequence round, and finishing one does not open a score or a match.
What you are being asked
A complete-the-sequence question stops the row early. You supply the next term only after the same rule fits every step you can already see.
Two further question types are planned for the game: find the term that breaks the rule, and name the rule itself. The rows below are the first type. The method for reading gaps, products, and interleaved lists is the guide, not this index.
On this page
- 2, 6, 12, 20, 30, ?
The gaps grow by two each time. The next term is checked on the page.
- 8, 11, 15, 20, 26, ?
A different growing gap, written for this index.
