This is so crazy!!! Weakness of inductive reasoning at best! Now who discover that it didn't work for such big n? and more importantly HOW? #math #proofbyinduction #Blowmymind

Prove 2³ᴺ-1 is divisible by 7 ∀N∈ℕ Observe true for N=1 2³-1=8-1=7 divisible by 7 Assume true for N=1,..,k So 2³ᵏ-1=7a for a∈ℕ Prove true for N=k+1 2³⁽ᵏ⁺¹⁾-1=2³ᵏ⁺³-1=2³ᵏx2³-1 =2³ᵏx8-1-7+7=2³ᵏx8-8+7 =8(2³ᵏ-1)+7=8(7a)+7 =7(8a+1) divisible by 7 #ProofByInduction
