A theater needs to place seats in rows. The function, f(r) as shown below can be used to determine the number of seats in each row, where r is the row number.
f(1) = 8
f(r) = f(r – 1) + 3
Use the function to complete the table indicating the number of seats in each row for the first four rows of the theater.
The row counts start at eight and count up by three:
[tex]f(1)=8[/tex] [tex]f(2)=f(2-1)+3=f(1)+3=8+3=11[/tex] [tex]f(3)=f(3-1)+3=f(2)+3=11+3=14[/tex] [tex]f(4)=f(4-1)+3=f(3)+3=14+3=17[/tex] . . . and so on.
