X% increments for each year

I know it's something so simple. I'm just overthinking it right now it will probably come back to me later on. Help is appreciated though, thanks.

The total accumulated amount, after 20 years at 10% of an intial $2000 investment will be $13,454.

After one year, a gain of $200 would be recorded, to yield a total after 1st year of $2200...and so on till year 20.
