Coach Beasley made a deposit of $1,800 into an account that earns 2% annual compound interest. Find the amount of interest that Coach Beasley earned after 3 years. Which formula would you use to solve this?

This is what i found “an explicit formula designates the nth term of the sequence, as an expression of n (where n = the term's location). it defines the sequence as a formula in terms of n. this example is an arithmetic sequence(the same number, 5, is added to each term to get to the next term).” i hope this you for what your looking for. can you plz mark me brainliest?
