(" is a way of saying minus.) -06) lim sz (f) = CERT lim wlf) = 0 1700 Three Point Extra Credit: The Fibonacci sequence is a sequence of numbers in which each number is the sum of the two preceding numbers. More formally. Fil01. 2.) is defined as follows Fo=0, F1 = 1, and Vk 2, F = F-1 + F-2. The infinite sequence is: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34. ... Based on the definition, prove that 2F1-Fi + F 2 fork 2 2. Note: it is not necessary to use induction
