One of the screens in a movie theater has 14 seats in the first row, and each row after the first has 3 more seats than the previous row. Nolan says the expression 3n +14 could be used to find A, the number of seats in the nth row of the screen in the theater. Examine Nolan’s explicit expression to explain whether he is correct. If Nolan is not correct, formulate the correct explicit expression.
