An amphitheatre has 24 seats in the first row, 28 in the second, 32 in the third, and so on, for 29 rows. how many seats are in the amphitheatre?

The answer is 2,320 seats in the amphitheater. Since the seats are increasing at a rate of 4 more seats each row, then just add 4 to the number for each past row starting at 32 since that's where the rest is unknown. Once you find all he numbers just add them up to get your answer.
I hope I helped!
