WebFeb 18, 2010 · Hi, I am having trouble understanding this proof. Statement If p n is the nth prime number, then p n [tex]\leq[/tex] 2 2 n-1 Proof: Let us proceed by induction on n, the asserted inequality being clearly true when n=1. As the hypothesis of the induction, we assume n>1 and the result holds for all integers up to n. Then p n+1 [tex]\leq[/tex] p 1 ...

WebSep 10, 2024 · Proof by cases – In this method, we evaluate every case of the statement to conclude its truthiness. Example: For every integer x, the integer x (x + 1) is even Proof: If x is even, hence, x = 2k for some number k. now the statement becomes: 2k (2k + 1) which is divisible by 2, hence it is even. http://www2.math.umd.edu/~shalper/text.pdf
WebMost of the steps of a mathematical proof are applications of the elementary rules of logic. This is a slight oversimplification, as there are a great many proof techniquesthat havebeen developedover thepast two centuries.
