in 2013, the number of people living in a small town was 284. it was estimated that the towns population would increase by 4%

The situation can be modeled by a geometric sequence with an initial term of 284. The student population will be 104% of the prior year, so the common ratio is 1.04.
Let
P
P be the student population and
n
n be the number of years after 2013. Using the explicit formula for a geometric sequence we get

We can find the number of years since 2013 by subtracting.

2020−2013=7
We are looking for the population after 7 years. We can substitute 7 for
