WebConclusion: using the principle of Mathematical Induction conclude that P(n) is true for arbitrary n 0. Variants of induction: (although they are really all the same thing) Strong Induction: The induction step is instead: P(0) ^P(1) ^:::^P(n) =)P(n+ 1) Structural Induction: We are given a set S with a well-ordering ˚on the elements of this set.
