wrong forum i think.
You did not say whether the casflows happen at the start or the end of each year. I will assume they happen at the start of each year.
Using standard notation
i = annual interest rate
you want to solve PV = 0
Use trial and error. For a first guess i will use 10%
@ 10%: PV = 2099
@ 20%: PV = -213
So the answer is between 10% and 20%. it looks closer to 20%
So the answer is between 19% and 20%
Keep going and you will get 19.2%
