When n = 1 first term = -6
n = 2 second term = 0
n = 3 third term = 6
n = 4 4th term = 12
so we have an Arithmetic sequence first term = -6 and common difference = 6
Sum 14 terms = (14/2)[2*-6 + (14-1)*6]
= 462 answer

As te car gets older the value depreciates because it gets used and put through rough roads or accidents. the newer the car is the better shape it is in and the higher value it would have.
