Functional equation sum | Tips in the description #functions

A real interesting functional equation problem. The goal is to find the value of the sum f(2)+f(4) + ... + f(200).
Tip No1 : set x=0 to find f(0) .
Tip No2 : Prove that f(x) = f(x+2) for every real number x. #shorts #maths #tips #tricks #functions #equations
