WebAug 25, 2024 · So I came across this formula of Fibonacci numbers as a binomial sum [1] [2] F n = ∑ k = 0 ⌊ n − 1 2 ⌋ ( n − k − 1 k) I'm not really sure that this formula actually valid, I've computed some of the first terms and they don't look very much like Fibonacci numbers to me. Maybe the identity is wrong, but several places have it stated ... WebWe will now look at some rather useful identities regarding the binomial coefficients.
