#What is the fibonacci sequence in nature series

The rabbits labelled with a Fibonacci number are the children of the original rabbit (0) at the top of the tree.Thus 5, 6 and 7 are the children of 0, 1 and 2 respectively. The rabbits have been uniquely numbered so that in the same generation the new rabbits are numbered in the order of their parent's number.All the rabbits born in the same month are of the same generation and are on the same level in the tree.Rabbits have been numbered to enablecomparisons and to count them, as follows: Now can you see why this is the answer to ourRabbits problem? If not, here's why.Īnother view of the Rabbit's Family Tree:īoth diagrams above represent the same information. The first 300 Fibonaccinumbers are here and some questions for you to answer.

#What is the fibonacci sequence in nature series

Ĭan you see how the series is formed and how it continues? If not,look at the answer! The number of pairs of rabbits in the field at the start of each month is 1, 1, 2, 3, 5, 8, 13, 21, 34. At the end of the fourth month, the original female has produced yet another new pair, the female born two months ago produces her first pair also, making 5 pairs.At the end of the third month, the original female produces a second pair, making 3 pairs in all in the field.At the end of the second month the female produces a new pair, so now there are 2 pairs of rabbits in the field.At the end of the first month, they mate, but there is still one only 1 pair.How many pairs will there be in one year? Suppose that our rabbits never die and thatthe female always produces one new pair (one male,one female) every month from the second month on. Rabbits are able to mate at the age of one month so thatat the end of its second month a female can produce another pair ofrabbits. Suppose a newly-born pair of rabbits, one male, one female, areput in a field. Fibonacci's RabbitsThe original problem that Fibonacci investigated (in the year1202) was about how fast rabbits could breed in ideal circumstances. This introduces you to the Fibonacci Numberseries and the simple definition of the whole never-ending series. Rabbits, Cows and Bees Family TreesLet's look first at the Rabbit Puzzle that Fibonacci wrote about and then at twoadaptations of it to make it more realistic.
