Proof by Induction is one of the most elegant and powerful techniques in mathematics — yet it’s also one that confuses many students at first.
Whether you’re preparing for IB, A-Level, AP, JEE, Olympiads, or simply want to build a rock-solid foundation in pure math, this guide will help you understand how induction works, when to use it, and how to avoid common pitfalls.
🔍 What is Proof by Induction?
Proof by induction is a method of mathematical proof used to show that a statement holds true for all natural numbers (or a sequence of values). It works in two main steps:
- Base Case – Show that the statement is true for the first value (usually n=1n = 1n=1).
- Inductive Step – Assume it’s true for n=kn = kn=k, and then prove it’s true for n=k+1n = k+1n=k+1.
If both steps hold, then the statement is proven for all natural numbers!
💡 Why Students Struggle
- Confusing assumption vs conclusion in the inductive step
- Forgetting to verify the base case
- Incorrect algebra when proving P(k+1)P(k+1)P(k+1)
- Misidentifying when induction is even appropriate
