Their generating function is x divided by 1 minus x minus x squared, and every positive integer can be written as the sum of non-consecutive ones of these according to Zeckendorf's theorem. The Lucas numbers obey a similar rule as them, and one formula for generating them relies on the Golden Ratio, known as Binet's formula. Defined recursively by summing the previous two numbers in the sequence, for 10 points, name these numbers that begin 1, 1, 2, 3, 5…
