A sequence is called a solution of a recurrence relation if its terms satisfy the recurrence relation. The initial conditions for a sequence specify the terms that precede the first term where the recurrence relation takes effect. Rabbits and the Fiobonacci Numbers Example: A young pair of rabbits (one of each gender) is placed on an island. A pair of rabbits does not breed until they are 2 months old. After they are 2 months old, each pair of rabbits produces another pair each month. Find a recurrence relation for the number of pairs of rabbits on the island after n months, assuming that rabbits never die. This is the original problem considered by Leonardo Pisano (Fibonacci) in the thirteenth century. Rabbits and the Fiobonacci Numbers (cont.) Modeling the Population Growth of Rabbits on an Island Rabbits and the Fibonacci Numbers (cont.) Solution: Let fn be the the number of pairs of rabbits after n months. There are is f1 = 1 pairs of . | Advanced Counting Techniques Chapter 8 With Question/Answer Animations Copyright © McGraw-Hill Education. All rights reserved.
