What this test measures
Correct and incorrect answers indicate knowledge of the concepts in this practice. They do not establish a trait profile, diagnosis or job fit.
- For a number sequence, calculate the differences between neighboring terms before guessing the next term.
- If one rule does not fit, split odd and even positions into two smaller sequences.
- A short sequence can support many invented rules. In these exercises, look for the simple rule that explains every shown term.
| Category | Questions in bank | What it covers |

A worked example
What comes next: 4, 9, 16, 25, ?
- The differences are 5, 7 and 9. A difference of 11 would give 36.
- There is a second check: the terms are 2², 3², 4² and 5².
- Both simple methods point to 6² = 36.
