## Terminology of Second Principle of Finite Induction

### Basis for the Induction

The step that shows that the integer $n_0$ is an element of $S$ is called the basis for the induction.

### Induction Hypothesis

The assumption that $\forall k: n_0 \le k \le n: k \in S$ for some $n \in \Z$ is the induction hypothesis.

### Induction Step

The step which shows that $n + 1 \in S$ follows from the assumption that $k \in S$ for all values of $k$ between $n_0$ and $n$ is called the induction step.
