Webbconjecture the following formula: 1 3+ 2 + 1+ n3 = 4 n4 + 1 2 n3 + 1 4 n2: Finding this formula was the hard part. It is now not so hard to prove this formula by induction: Proof. We will prove that (8) 1 3+ 2 + 1+ n3 = 4 n4 + 1 2 n3 + 1 4 n2: by induction on n. The case n= 0 is clear, because both sides of the equation are equal to 0. If (8 ... Webb5 jan. 2024 · 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. When n = 1: 4 + 14 = 18 = 6 * 3 Therefore true for n = 1, the basis for induction.
