The first payment is 5,000 in one year's time. PV = 5,000/1.04
The second payment is 5,000*1.04 in 2 years' time. PV = 5,000/1.04
The 3rd payment is 5,000*1.04^2 in 3 years' time. PV = 5,000/1.04
Every payment has a PV = 5,000/1.04.
We get each payment if we survive a whole year. So EPV = 5,000e65/1.04
Good luck!
