Fibonacci Sequence

If you ever looked at the seeds of a sunflower you will notice that they will follow a pattern that spirals out.

If you count it, the seeds would spiral out this way:

1,1,2,3,5,8,13,21,34,55,89,...

This is the Fibonacci Sequence. To find next value just add the two preceding values, e.g.

1+1=2
1+2=3
2+3=5
.
.
.
FOREVER!

This pattern is all over in nature: in sunflowers and and in pinapples to name a few.
