Does anyone know of a function that can provide the the starting payment and
the subsequent payments thereafter to reach a total as defined.

Example:
Total payments must be 5000 over 5 years. The increase rate is 10% every
year, so what will the starting payment be.

I have been able to figure this out using Algebra type mathematical
formula's in excel, however i believe there must be a function that can very
easily achieve this more quickly. The field Total payments, no of payments
and increase rate is known, while the unknown is the starting payment and the
payments subsequent to that.
