The Fibonacci Sequence The sequence of numbers 1,1,2,3,5,8….in which each successive number is equal to the sum of the two preceding numbers.

Leonardo Fibonacci Leonardo Fibonacci was born in {1170}and died in{1240}.He came up with a challenging question about a pair of rabbits.

The Question Two rabbits male and female were just born and put in a field .They can mate with each other and they never die. And that they can reproduce at one month old. Each female rabbit produces one pair male, and female each time they mate . If this happens how many rabbits will there be at the end of each month?

The Answer The answer would be 1,1,2,3,5,8,13,21,34,55,89,and on, and on, and on, and on.

Where In Nature Is it Found??? The Fibonacci Sequence is found in many ways in nature. EX. The petals on a flower, and the seeds on a sunflower.

Petals on a flower Buttercups have 5 peatles,lilies,iris,clover{mostley} have 3 petals corn marigolds have 13 asters with 21 daises with 21 34 or 89

The End You can probably see that the Fibonacci sequence is important mathematically and in nature.
