The numbers that appear in the sequence below are called Fibonacci number.
1
1, 1, 2, 3, 5, 8, 13, 21, ....The Fibonacci sequence can be determined by the rule F₁ = 1, F₂ = 1 and
Fn = Fn-1 + Fn-2. Using this result and a method of induction, prove F2+1 − Fn+1Fn − F2² = (-1)" for
any natural number n.
