Tool to compute numbers of Fibonacci. Fibonacci sequence is a sequence of integers, each term is the sum of the two previous ones.

Numbers from the Fibonacci sequence are equal to the addition of the 2 previous terms, they follow the recurrence formula: $$ F(n+2) = F(n) + F(n+1) $$

To initiate the sequence, one takes F(0) = 0 and F(1) = 1

F2 = F0+F1 = 0+1 = 1

F3 = F1+F2 = 1+1 = 2

F10 = F8+F9, etc.

F(0)= | 0 |
---|---|

F(1)= | 1 |

F(2)= | 1 |

F(3)= | 2 |

F(4)= | 3 |

F(5)= | 5 |

F(6)= | 8 |

F(7)= | 13 |

F(8)= | 21 |

F(9)= | 34 |

F(10)= | 55 |

The rabbits' problem is a problem proposed by Fibonacci in 1200.

There is a rabbit couple (male + female) and every month a couple breeds and give birth to a new pair of rabbits which in turn can reproduce itself after 2 months. How many rabbits will be born after X months?

In the beginning there is 1 couple then

1 month | 1 couple |

two months | 2 couples |

three months | 3 couples |

4 months | 5 couples |

5 months | 8 couples |

6 months | 13 couples |

7 months | 21 couples |

8 months | 34 couples |

Each month, the total number of rabbits is equal to the sum of the numbers of the previous two months because it is the number of existing rabbits (the previous month) plus the number of babies born from rabbits couples who have at least two months (hence the number of rabbits 2 months ago). The numbers found are the numbers of the Fibonacci sequence.
