Question

A theater has 35 seats in the first row, 38 seats in the second row, 41 seats in the third row, and so on. How many seats are there in row 16?

There are
seats in row 16.

Answer 1

80

Explanation:

35 + 3(x-1) = Total Number of Seats where x represents the row.

35 represents the number of seats in the first row.

3(x-1) represents the three seats added every row after the first.

x = 16 row

35+ 3(16-1)

= 35 + 3*15

= 35+ 45

= 80
