WebJan 5, 2024 · As you know, induction is a three-step proof: Prove 4^n + 14 is divisible by 6 Step 1. When n = 1: 4 + 14 = 18 = 6 * 3 Therefore true for n = 1, the basis for induction. It is assumed that n is to be any positive integer. The base case is just to show that \(4^1+14=18\) is divisible by 6, and we showed that by exhibiting it as the product of 6 ...

Proof by induction has four steps: Prove the base case: this means proving that the statement is true for the initial value, normally \(n = 1\) or \(n=0.\); Assume that the statement is true for the value \( n = k.\) This is called the inductive hypothesis.
WebJan 11, 2024 · Proof By Contradiction Examples - Integers and Fractions. We start with the original equation and divide both sides by 12, the greatest common factor: 2y+z=\frac {1} {12} 2y + z = 121. Immediately we are struck by the nonsense created by dividing both sides by the greatest common factor of the two integers.
