Trouble with annuity time lines
A 30year annuity is arranged to pay off a loan taken out today at a 5% annual effective interest rate. The first payment of the annuity is due in ten years in the amount of 1,000. The subsequent payments increase by 500 each year.
Calculate the amount of the loan. I tried doing this problem like this: (v^10)*(1000 a double dot angle 30 at 5% + 500 Ia angle 29 at 5%), but something's wrong. Could anyone please explain? Thank you.

Try this
1000 + 500/.05 PMT  30 x 500/.05 FV 30 N 5 I/Y CPT PV FV 0 PMT 9 N CPT PV
