To find the number of seats in row 15, we can use the formula for the number of seats in a row n:
Number of seats = 33 + (n-1) * 3
Plugging in n = 15:
Number of seats = 33 + (15-1) * 3
Number of seats = 33 + 14 * 3
Number of seats = 33 + 42
Number of seats = 75
Therefore, there are 75 seats in row 15.
A theater has 33 seats in the first row, 36 seats in the second row, 39 seats in the third row, and so on. How many seats are there in row 15?
