The number of cars sold weekly by a new automobile dealership grows according to a linear growth model. the first week the dealership sold six cars (po=6). the second week the dealership sold cars ( p1 = 14 ). write the recursive formula for the number of cars sold, pn , in the ( n + 1 )th week. pn = pn − 1 + write the explicit formula for the number of cars sold, pn , in the ( n + 1 ) week. pn = if this trend continues, how many cars will be sold in the sixth week?
