This is my excel assignment,
Problem:
$1 is paid at the end of every year for 50 years. Assume an interest rate of 5% unless otherwise noted.
1. Calculate the value of the annuity at t = 25 using the following methods:
a. Sum up the value of each individual payment
b. Use the annuity formulas
c. Use the excel formulas
I have lack of understanding how to find the values when the time is specific as the problem has t=25.
