The generating function x divided by the quantity 1 minus x minus xsquared creates these numbers.
One method of testing whether a number n is one of these involves asking whether 5n squaredminus 4 or 5n squared plus 4 is a perfect square. One method of generating these numbers is torepeatedly take powers of the two-by-two matrix one-one-one-zero, and the Wall-Sun-Sun primes aredefined using these numbers. The generating function x divided by the quantity 1 minus x minus xsquared creates these numbers. Taken modulo some integer n these numbers gives rise to (*) Pisanoperiods. The ratio between successive members of these numbers approaches 1 plus the square root of 5 allover 2, which is known as the golden ratio. For 10 points, name this sequence of numbers, a given memberof which is a sum of the previous two entries.
