Prove a summation by induction
Webb15 maj 2009 · Here is a explanation by example: Let's say you have the following formula that you want to prove: sum (i i <- [1, n]) = n * (n + 1) / 2. This formula provides a closed form for the sum of all integers between 1 and n. We will start by proving the formula for the simple base case of n = 1. In this case, both sides of the formula reduce to 1. WebbProve by (strong) induction that the sum of the first n Fibonacci numbers f 1? = 1, f 2? = 1, f 3? = 2, f 4? = 3, ...
