WebI am trying to use induction to prove that the formula for finding the n -th term of the Fibonacci sequence is: Fn = 1 √5 ⋅ (1 + √5 2)n − 1 √5 ⋅ (1 − √5 2)n. I tried to put n = 1 into the equation and prove that if n = 1 works then n = 2 works and it should work for any number, but it didn't work. WebMar 24, 2024 · TOPICS.
