What this assessment looks like
A pattern-recognition screen: a list of numbers hiding a rule - arithmetic, geometric, alternating, second-order differences, or interleaved sequences - and you supply the next term before the clock runs out.
- First and second differences, ratios, and alternating patterns
- Interleaved sequences (two rules taking turns)
- Squares, cubes, primes and factorials recognised on sight
- Committing to an answer with seconds left
Train it here
- Sequence Sprint - Timed next-term sequences, exactly the assessment format.
- Arithmetic Drill - The raw calculation speed that sequence tests assume you already have.
