Binets formula by induction
WebFeb 16, 2010 · Hello. I am stuck on a homework problem. "Let U(subscript)n be the nth Fibonacci number. Prove by induction on n (without referring to the Binet formula) that U(subscript)m+n=U(subscript)m-1*U(subscript)n + U(subscript)m *U (subscript)n+1 for all positive integers m and n. WebTheorem (Binet’s formula). For every positive integer n, the nth Fibonacci number is given ex-plicitly by the formula, F n= ˚n (1 ˚)n p 5; where ˚= 1 + p 5 2: To prove this theorem by mathematical induction you would need to rst prove the base cases. That is, you rst need to prove that F 1 = ˚ 2(1 ˚) p 5, and that F 2 = ˚2 (1 ˚) p 5 ...
