Need to lend a tenner?

No interest ever.

Just a fee for my end,

A third of what I lend.

Falling short of the fee?

I will lend it to thee!

What do I lend you all together?

  • $\begingroup$ @RosieF it has the British lower-class usage of "lend" to mean borrow $\endgroup$ – Grump. Sep 29 '19 at 7:33

Here goes!

From the origins of a tenner
We have a geometric progressor
To 10 we add its third
And to this we add its third
This continues for infinity
With 15 as its affinity
And so it's a tenner times three over two
As the amount I now owe to you.
