Can you check, because I am probably wrong.

You are wrong. How can one invest 2000 dollars at a modest rate of interest for two years and get a half-million dollars?

Post your work, I will check.

Instead of calculating interest year-by-year, it would be simple to see the future value of an investment using a compound interest formula. The formula for compound interest is:

Pn = P0(1 + I)n

where:
Pn = Value at end of n time periods
P0 = Beginning Value
I = Interest
n = Number of years
