This is the Fibonacci sequence, named after its medieval discoverer,Leonardo Fibonacci da Pisa. The series is produced by starting with 1 and adding the last two numbers to arrive at the next.
1,1,2,3,5,8,13,21,34, ....
This set of numbers holds a certain fascination for many students of nature. The spiral ratio of a daisy head shows 21spirals in a clockwise direction, 34 counter-clockwise. This ratio is found in the Fibonacci sequence, 21:34
In a pine cone, it is 5:8. In a pineapple it is 8:13Many other plants with a spiral leaf-growth pattern also exhibit Fibonacci ratios.
Fibonacci numbers also show up in art and architecture. The ratio between any two adjacent numbers after 3 is 1:1.6 . This is the so-called Golden Ratio.

That is the fibonacci series. you start by adding numbers in sequence to get it. the next number is 5+8=13, then so on.
