Hi,

I'm trying to locate a formula for calculating the first payment in a growth annuity where the following is known:

1) The Future Value of the Annuity

2) The growth rate

3) The interest rate.

4) Number of Periods

Can anyone assist with this, It's starting to do my head in.

Thankyou & Regards,

Nick.

PS: I've attached a simple spreadsheet illustrating what I'm trying to do (but it may make things even more confusing!)
