Proof by Induction Induction is a method for proving universally quantified propositions—statements about all elements of a (usually infinite) set. Induction is also the single most useful tool for reasoning about, developing, and analyzing algorithms. These notes give several examples of induct...

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...

If k = 0, then 1\equiv 1 \pmod{n}, and for the induction step, suppose that a^k\equiv b^k\pmod{n}, then we have a^{k+1}= a\cdot a^k \equiv b \cdot b^k = b^{k+1} \pmod{n}.This theorem is useful for carrying out computations modulo n. Here are some examples....
At this point, to be able to show that n is divisible by 3, we need to prove that 10s−1 is divisible by 3 for all s≥ 1. This is the step that can require proof by induction (see Exercise 38 at the end of the section on Mathematical Induction) unless one is familiar with mo...
