SUMMARY

The discussion focuses on proving the Fibonacci sequence identity f(m+k) = f(m-1) * f(k) + f(m) * f(k+1) using mathematical induction. The key equation f(k+1) = f(k) + f(k-1) serves as the foundation for the proof. Participants express challenges in transitioning from addition to multiplication within the Fibonacci context, particularly when introducing two variables into the induction process. The conversation highlights the complexities of Fibonacci relationships and the need for a structured approach to induction proofs.

Homework Statement



Proof by induction of the following: f(m+k) = f(m-1)* f(k) + f(m) * f(k+1)

Homework Equations



f(k+1) = f(k) + f(k-1)

The Attempt at a Solution



The only way I can figure to get multiplication from addition was to square both sides, but then I really get out of my league.

What is the relationship if you double a fib. #?

Do you know how to get induction started when you have two variables?
 
No i think that is my first issue here
