Look at each number series, identify its rule and choose the answer that continues the pattern. The puzzles use simple operations and relationships.

The rounds are designed around reasoning rather than random trivia. Your best score is saved locally in your browser.

What patterns can you find?

You may encounter additions, multiplications, differences and combinations of rules. Read the full sequence before choosing an answer and check the explanation afterwards.

For a different challenge, try memory, words, Wordle or the daily challenge.

GUIDE PRATIQUE

How to solve number sequences

Look for a simple rule that explains every step, not just the last two numbers. Check your idea against the whole sequence before choosing.

A three-step method

First, calculate the differences between consecutive numbers. If there is no clear pattern, check whether the values are multiplied or divided by a constant. Finally, consider whether the differences themselves follow a sequence.

Avoid rushing into an answer

A short series can fit several imaginable rules. Use the answer choices and the explanation after each round to identify the intended rule and learn from mistakes.
