What the Number series reasoning is

A short run of numbers hides a rule — doubling, alternating steps, squares — and you pick what comes next before the timer dies. Number-series items are a staple of inductive-reasoning tests going back nearly a century, because inferring a rule from examples is about as close as a quiz can get to raw reasoning.

What it measures

Each solved pattern is a small act of hypothesis-testing under time pressure: propose a rule, check it against every gap, commit. It feeds decision-making — the deliberate end of the axis is exactly the person who verifies the rule twice before tapping.

Impulsive

You go on gut and sort it out on the way down.

Balanced

You'll plan the big stuff and wing the rest.

Deliberate

You see the whole board before you touch a piece.

Why hiring assessments use it

Sequence items survive in modern assessments because they're stubbornly hard to fake and barely coachable: you either extract the rule in fourteen seconds or you don't.

TELLS is an independent project — not affiliated with pymetrics, Harver, or any employer's assessment. This is the fun version.
