• Number series. Find the rule behind a list of numbers and give the next one.

How the drill works

You get a set of ten questions at the level you choose, easy, medium or hard. Every set is generated fresh, so you can keep going without seeing the same question twice. After each answer you see the working. When you pick a wrong answer, the explanation names the slip that usually leads to it, so you can spot it next time. Drills are for practice only: Wittlo makes no claim about exam results.
