Overview

Mathematical induction is a powerful proof technique used in mathematics to establish the truth of statements that apply to all natural numbers or a sequence of natural numbers. Unlike deductive reasoning, which applies general rules to specific cases, induction builds general truths from specific o

Key Concepts

A mathematical statement (or proposition)

A mathematical statement (or proposition) is a sentence that is either definitely true or definitely false, but not both. For example, '5 is even' is

The Principle of Mathematical Induction states

The Principle of Mathematical Induction states: Let P(n) be a statement involving a natural number n. If (i) P(1) is true (base case), AND (ii) whenev

The base case is the first

The base case is the first step in a proof by mathematical induction. We verify that the statement P(1) is true by direct substitution or calculation.

The inductive step involves two parts

The inductive step involves two parts: (1) assuming P(k) is true for some arbitrary natural number k (this assumption is called the inductive hypothes

Every proof by mathematical induction follows

Every proof by mathematical induction follows three steps: (1) State the statement clearly as P(n). (2) Verify the base case by showing P(1) is true (
