WebRecap: Modular Arithmetic Definition: a ≡ b (mod m) if and only if m a – b Consequences: – a ≡ b (mod m) iff a mod m = b mod m (Congruence ⇔ Same remainder) – If a ≡ b (mod m) and c ≡ d (mod m), then a + c ≡ b + d (mod m) ac ≡ bd (mod m) (Congruences can sometimes be treated like equations) WebIn most proofs by induction, in the induction step we will try to do something very similar to the approach here; we will try to manipulate P(n+1)in such a way as to highlight P(n)inside it. This will allow us to use the induction hypothesis. Here are now some more examples of induction: 1. Prove that 2n

WebThe steps in between to prove the induction are called the induction hypothesis. Example Let's take the following example. Proposition 5+10+15+...+5n = \frac {5n (n+1)} {2} 5 + 10+ 15 +... + 5n = 25n(n+1) is true for all positive integers. Proof Base case Let n=1 n = 1. Replace the values in the equation: Webthe structure of complete induction. For example, for n = 0, the inductive hypothesis does not provide any information — there does not exist a natural number n′ < 0. Hence, F[0] must be shown separately without assistance from the inductive hypothesis. Example 4.3. Consider another augmented versionof Peanoarithmetic, T∗ PA,

WebInduction Hypothesis: For some arbitrary n =k ≥0, assume P(k). Inductive Step: We prove P(k +1). Specifically, we are given a map withk +1 lines and wish to show that it can be two-colored. Let’s see what happens if we remove a line. With only k lines on the map, the Induction Hypothesis says we can two-color the map. Web(In the instantiation of the formula for well-founded induction this is the only case where there are no R-“smaller” elements y.) Inductive Step:Show that P(k) !P(k + 1) is true for all k 2N.
