Proof by induction has four steps: Prove the base case: this means proving that the statement is true for the initial value, normally \(n = 1\) or \(n=0.\); Assume that the statement is true for the value \( n = k.\) This is called the inductive hypothesis. WebSep 11, 2015 · The proof is a trick, of course. Working in the opposite direction, the idea is to write 2 ∑ r = 1 n r = ∑ 2 r = ∑ ( ( 2 r + 1) − 1) = ∑ ( 2 r + 1) − ∑ 1 = ∑ ( 2 r + 1) − n This seems elaborate, but the point is to write as much of the sum as possible in a form which cancels. secretly greatly yts
