WebbMathematical induction is a proof method often used to prove statements about integers. We’ll use the notation P ( n ), where n ≥ 0, to denote such a statement. To prove P ( n) with induction is a two-step procedure. Base case: Show that P (0) is true. Inductive step: Show that P ( k) is true if P ( i) is true for all i < k.

WebbInduction says that to prove some condition K about every object in a set, we need to prove 2 things: 1.) That K is true for n = 1 2.) If K is true for n = i, then it is true for n = i + 1 This seems like a bit of a leap, but lets try to get an intuition for why these are the two (and the only two) conditions needed.
