WebThus we can write the sum of even integers less than or equal to n as. ∑ k = 0 ⌊ n / 2 ⌋ 2 k. If you stare hard enough at this you'll see why it works: if n is even then ⌊ n 2 ⌋ = n 2, so the last term is 2 ⋅ n 2 = n. If n is odd then ⌊ n 2 ⌋ = n − 1 2, so the last term is 2 ⋅ n − 1 2 = n − 1. Share.
