Fibonacci

There once was a young lad from Pisa,

Whose sequence of numbers would please ya.

He had a strange habit

Of watching the rabbits;

"Their numbers are nothing to sneeze at!"

 

This sequence we'll frequently see,

On the piano - the black or white key,

With daisies and pinecones,

And the Nautilus' shell-home,

And the male honey bee's family tree.

 

So what makes his sequence so great?

His terms we must now calculate:

We start with two ones,

Then, find their sum,

And go: 1, 1, 2, 3, 5, and 8!

 

So. Fibonacci, your sequence continues

To turn up in all sorts of venues.

No cause for concern,

But consecutive terms

Give a ratio that's Golden, 1.62!
