The table shows the value of Andy’s car for each of the first 3 years after it is purchased. The values form a geometric sequence. What will be the approximate value of the car in the 10th year?

• $3,328

• $2,662

• $4,160

• $4,960

Answer explanation

The geometric pattern is found by discovering what percentage of the value is being lost each year. (19840/24800 = .8 so the car is losing 20% per year) Verify that by multiplying 19840*.8 and you will get 15872. Follow the process/pattern until you have reached the 10th year.
