Of the 189 miles of beaches at ocean side, 7% are privately owned 39% are owned by resorts, and 54% are public beaches. how many miles of beach are not public?

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?
