WebMathematical induction is a method of mathematical proof typically used to establish a given statement for all natural numbers. It is done in two steps. The first step, known as the base case, is to prove the given statement for the first natural number. WebJan 5, 2024 · Hi James, Since you are not familiar with divisibility proofs by induction, I will begin with a simple example. The main point to note with divisibility induction is that the objective is to get a factor of the divisor out of the expression. As you know, induction is a three-step proof: Prove 4^n + 14 is divisible by 6 Step 1.
