To prove this you would first check the base case n = 1. This is just a fairly straightforward calculation to do by hand. Then, you assume the formula works for n. This is your "inductive hypothesis". So we have. ∑ k = 1 n 1 k ( k + 1) = n n + 1. Now we can add 1 ( n + 1) ( n + 2) to both sides:

WebP(0), and from this the induction step implies P(1). From that the induction step then implies P(2), then P(3), and so on. Each P(n) follows from the previous, like a long of dominoes toppling over. Induction also works if you want to prove a statement for all n starting at some point n0 > 0. All you do is adapt the proof strategy so that the ... Web2 Weak Mathematical Induction 2.1 Introduction Weak mathematical induction is also known as the First Principle of Mathe-matical Induction and works as follows: 2.2 How it Works Suppose some statement P(n) is de ned for all n n 0 where n 0 is a nonnegative integer. Suppose that we want to prove that P(n) is actually true for all n n 0.
