You are negotiating to make a 6-year loan of $40,000 to Breck Inc. To repay you, Breck has agreed to pay 5,000 at the end of Year 1, $10,000 at the end of Year 2and $15,000 at the end of Year plus a fixed but currently unspecified flow, "", at the end of each year from Year 4 through Year 6. 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 6 year loan. What cash flow must the investment provide at the end of each of the final 3 years to satisfy your return requirement? (i.e. what is "X"?)
