The Fibonacci sequence was discovered by Leonardo Fibonacci. He discovered the sequence when he was looking at how different generations of rabbits breed.

WHERE IT CAN BE FOUND

  • The fibonacci sequence can be found in every living cell
  • It can be found in things like;
  • Flowers, pinecones
  • Apples, bananas,
  • Fingers, arms,

To find the next number in the sequence, you add the the two previous numbers before the number.
0+1=1
1+1=2
1+2=3

This is how the sequence works

Fact
When you take to consecutive numbers in the Fibonacci sequence their ratio is very close to the golden ratio, which is about 1.618034...
