This is an example of a geometric equation. We can write this as:


y=6400(1.295)^x           where x is the number of years past.

In this case, x is one, as one entire year passed. 

Do the math, and you get 8288 at the end of the year. 

If you subtract 6400 from 8288, you get 1888. That is the difference.
