Question

Someone please please please help me!

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.

Answer 1

Nolan is right.

Explanation:

14 seats initially so thats your starting number, the +14 has to be there. He is right in saying +3n because it adds 3 every succeeding row. It would be 3 ×2 if its the second row, so 6 plus 14 equals 20 for example
