Hi Dan, no I haven't graphed it because what I need is the underlying equasion for the attached table and then I can adapt it to calc different multiples of weeks and parts thereof.

Present value of $1 a week from now is .9989 which means there is an interest rate of .11% per week. An annuity is the present value of a series of payments.

The resulting equation is a series depending on how many weeks you want to sum:

$\displaystyle \sum_{k=1}^{n+1} \frac{1}{1.0011^k}$
