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 (-5[1])also applies to similarly (-5[1])defined Lucas numbers. (10[1]-5[1])Consecutive pairs (10[1])of these numbers (10[1])give the worst run time for Euclid's algorithm. 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. (10[2])The population growth of rabbits was modeled using these numbers by their Italian namesake. For 10 points, (10[1])name this sequence of numbers defined by (10[1])adding the previous two numbers, (10[1])which starts 1, (10[1])1, 2, 3, 5. ■END■
