These numbers can be calculated using Vajda’s and Catalan’s identities. The uniqueness of some divisors of these numbers is implied by Carmichael’s theorem, which also (10[1])applies to similarly (-5[1])defined Lucas numbers. Consecutive pairs of these numbers give the worst run time for Euclid's algorithm. (-5[1])These numbers can be calculated with Binet’s formula, which uses a constant equal to the average of one and the square root of five denoted phi. The population growth of rabbits was modeled (10[1])using these numbers by their Italian (10[1])namesake. For (10[1])10 points, (10[1])name this sequence of numbers defined (10[1])by adding the previous (10[1])two numbers, which starts 1, 1, 2, 3, 5. (10[1])■END■
