You need to accumulate $10,000. To do so, you plan to make deposits of $1,250 per year with the first payment being made a year from today into a bank account that pays 12% annual interest. Your last deposit will be less than $1,250 if less is needed to round out to $10,000. How many years will it take you to reach your $10,000 goal, and how large will the last deposit be?
