You are negotiating to make a 7-year loan of $25000 to Breck Inc. To repay you Breck will pay $2500 at the end of Year 1 $5000 at the end of Year 2 and
$7500 at the end of Year 3 plus a fixed but currently unspecified cash flow X at the end of each year from Year 4 through Year 7. Breck is essentially
riskless so you are confident the payments will be made. You regard 8% as an appropriate rate of return on a low risk but illiquid 7-year loan. What cash flow
must the investment provide at the end of each of the final 4 years that is what is X?
