These notes give several examples of inductive proofs, along with a standard boilerplate and some motivation to justify (and help you remember) why induction works. 1 Prime Divisors: Proof by Smallest Counterexample A divisor of a positive integer n is a positive integer p such that the ratio...

TWO EXAMPLES OF PROOF BY MATHEMATICAL INDUCTION.DR. LOMONACOProposition: Use the principle of mathematical induction to prove that P (n) :nΣj=1j2 = n(n + 1) (2n + 1) 6 , for all integers n ^ 1. Proof (by weak induction): Basis Step: P(n) is true for n = 1, for:1Σj...
“We should consider a proof by contradiction, then.” Paulie shook his head. “I tried. It hasn’t gotten me anywhere. I reached out to a mathematician named Segami who’s been working on a proof by induction, though. It’s trivial fornequals one.” “Of course it is. Can you pro...
Induction is a method for proving general formulas by starting with specific examples. It's a way of proving that a formula is true "everywhere".

Proof Technique: Proof by Induction The method of proof by induction is used to show that a statement is true for all values of an integer variable greater than or equal to some initial value i. For example, A=“For every integer n⩾1,12+22+⋯+n2=n(n+1)(2n+1)/6” can be ...
