The Principle of Mathematical Induction states that if a proposition $P(n)$ is true for the base case (usually $n=1$) and if the truth of $P(k)$ implies the truth of $P(k+1)$ for any arbitrary integer k, then $P(n)$ is true for all natural numbers n.

Conditions: $P(1)$ is true.; For any k, $P(k)$ implies $P(k+1)$.; n is a natural number.
