Definition:Principle of Mathematical Induction/Basis for the Induction

Terminology of Principle of Mathematical Induction

Consider a Proof by Mathematical Induction.

The step that shows that the proposition $\map P {n_0}$ is true for the first value $n_0$ is called the basis for the induction.

Also known as

The basis for the induction is often informally referred to as the base case.
