The number of cars sold weekly by a new automobile dealership grows according to a linear growth model. The first week the dealership sold five cars ( P 0 = 5 ). The second week the dealership sold eleven cars ( P 1 = 11 ). Write the recursive formula for the number of cars sold, P n , in the ( n + 1 )th week. P n = P n − 1 + Write the explicit formula for the number of cars sold, P n , in the ( n + 1 )th week. P n = If this trend continues, how many cars will be sold in the 6th week?
