Hi folks,
I've been desparately trying to work out the underlying formula for the attached table. If someone could assist me in this, I would be grateful.
Thanks
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:
$\displaystyle \sum_{k=1}^{n+1} \frac{1}{1.0011^k}$
