40 mph would be 120 miles in 3 hours (120/40)
80 mph is 120 miles in 1.5 hours(120/80)
3 - 1.5 = 1.5, not 3 hrs
Change the speed to 20 mph( 1/2 the speed) to double the hours.
20 mph = 6 hours(120/20)
40 mph = 3 hrs(120/40)
6 - 3 = 3 hours difference
Any arithmetic sequence can be expressed as:
a(n)=a+d(n-1), a=initial term, d=common difference, n=term number
In this case a=5, and d=-2 so
a(n)=5-2(n-1) which can be simplified...
a(n)=5-2n+2
a(n)=7-2n
The domain is restricted to integers from 1 to +oo.

Answer:
$16,500
Step-by-step explanation:
The computation of the amount that should be paid for the car is shown below:
Since the car would be purchased one year ago
And, the value of the car would be decreased by 15% to $14025
So the amount that should be paid is
= $14025 × 100 ÷ (100 - 0.15)
= $16,500
