An auditorium has rows of seats that increase in length the farther the row is from the stage. The first row
has 28 seats, the second row has 35 seats, the third row has 42 seats, the fourth row has 49 seats, and so
on.
A) Let an be the number of seats in the nth row. Write an explicit formula of the form an = bn +c to
model this situation.
an =
B) Find ag =
C) If the last row has 189 seats, how many rows are there?
