Finally we show that if AM-GM holds for variables, it also holds for variables. By -variable AM-GM, Let Then we have So, By Cauchy Induction, this proves the AM-GM inequality for variables. tarot spread for wealthWebThe induction hypothesis is the following: “Suppose that for some n > 2, A(k) is true for all k such that 2 ≤ k < n.” Assume the induction hypothesis and consider A(n).
