How to play Sequence

A short number sequence appears with the final term missing. Work out the rule — it might add a constant, multiply, square, or follow a Fibonacci-style pattern — and pick the number that comes next from the four options. 60 seconds on the clock.

What it measures

Number-sequence problems test inductive and logical reasoning: inferring a hidden rule from examples and extending it. This 'fluid reasoning' is a core component of most IQ-style tests.

Honest note: You'll get sharper at these specific puzzle types with practice. That's a real, satisfying skill — not a guarantee of a higher IQ.

What's a good score?

Most people solve 12–20 in a minute; past 26 is quick reasoning. The percentile we show is an estimate based on typical distributions, not a clinical norm.

FAQ

What kinds of patterns appear?

Arithmetic (+n), geometric (×n), perfect squares, and Fibonacci-style sums.

Is there a penalty?

A wrong answer costs a point, so it pays to be sure before you tap.
