Fibonacci Numbers

There was a man from Italy

Who played with numbers cleverly

And though his last name was Bonacci

He is known as Fibonacci

In his book he wrote some numbers

That will make you count with wonder

For these numbers are unique

Count them now and you will see:

1 and 1 and 2 and 3

5 and 8 and then 13

After that comes 21

And still the list goes on and on

But why is this the way they go?

What comes next? How do we know?

What’s the order of the list

Listen and I’ll tell you this:

First you start with number 1

Then you count another 1

Adding those what do you get?

A 2 of course, so what comes next?

Well if you add the 1 and 2,

They make the number 3 for you

Then add the previous 2 to 3

You get a 5 and now you see

To get the number that we miss

You add the last two on the list

So now we add 3 to the 5

If you get 8, then you are right!

And here I’ll leave the rest to you

If you get lost this is the clue:

To get the number that you miss

Just add the last two on the list

And on forever you can count

Reaching numbers never found

Closer bit by bit we go

Towards the golden ratio...
