How can a number pattern help you test a claim?

A scaffolded investigation using small numbers to test a pattern. It does not attribute a quotation or a discovery to Sophie Germain.

Clue 1 · source detail

Fictional guide illustration · not evidence

Try a small number and record the result.

Show the steps so another reader can repeat them.

Clue 2 · source detail

Fictional guide illustration · not evidence

Compare several examples.

A pattern in a few cases suggests a question; it is not yet a proof.

Clue 3 · source detail

Fictional guide illustration · not evidence

Look for a case that does not fit.

One counterexample can disprove a universal claim.

Make your own theory

Before you peek, what do you think the clues show?

Write or discuss an explanation in your own words. Then compare it with the sourced case note below. This preview doesn’t save responses.

What a careful answer can say: Testing examples can help students notice a pattern and form a conjecture. A proof requires a reason the claim holds for every case in its stated domain.

What the evidence cannot settle: A handful of examples cannot establish a universal theorem or verify a historical claim about who first discovered it.
