so at the start of year 3 you have 5 plus 9% 5450
So you add 5000 and now you have 10450
after another year, beginning of year 4 you have 11390.50
and you add 5000 so you have 16390.5
at the end of year 4 you have 17865 plus 5000 for a total of 22865.
Use Future Value ordinary annuity "FVoa"...
FVoa = PMT[((1 + r)^n) - 1 / r]
= 5,000[(1.09^4) - 1) / 0.09]
= 5,000[0.41158 / 0.09]
= 5,000[4.57313]
= $22,865.65...a.k.a. not enough
