There is a long line of eager children outside of … WebThe Fibonacci numbers F n for n ∈ N are defined by F 0 = 0, F 1 = 1, and F n = F n − 2 + F n − 1 for n ≥ 2. Prove (by induction) that the numbers F 3 n are even for any n ∈ N. We all know what the Fibonacci numbers are, and I also know in general how proofs by induction work: assume for n case, prove by n + 1 case. Very nice!
