Custodians de setting up for a performance in an ampitheater. The 14th row the ampitheater has 60 seats, the 13th row has 56 seats, the 12th row has 52 seats and the 11th row has 48 seats. The
pattern of decreasing each successive row by 4 seats continues from the 11th row to the 1st row.
. f(r) = the number of seats in row r.
. f(1) = 8
Enter an equation, for r 2. that describes the number of seats, f(r). In the eth row in terms of the number of seats in the (r - 1) th row, f(r - 1). Assume that the pattern desribed applies to
all rows
