Now, \(f(n)=\frac{2k-2}{2}=k-1\). Because the integers are closed under subtraction, \(k-1 \in \mathbb{Z}\) so ... Web3.7: The Well-Ordering Principle. The Principle of Mathematical Induction holds if and only if the Well-Ordering Principle holds. Number theory studies the properties of integers. Some basic results in number theory rely on the existence of a certain number. The next theorem can be used to show that such a number exists.

WebClaim: Prove that for all natural numbers n, n2 − n is even. Proof attempt: If n2 − n is even, then n2 − n = 2k ⇒ n2 = 2k + n, for some k ∈ Z. Multiplying both sides by 2 we obtain 2n2 = 4k + 2n ⇒ 2n2 = 2(2k + n). Since k is some integer, 2k + n is also some integer. Let 2k + n = m. Therefore, 2n2 = 2m, which is even. ni no kuni cross worlds tippsWebSep 5, 2024 · Theorem 1.3.1: Principle of Mathematical Induction.
