Answer:

a(11) = 4^10 = 1048576

Step-by-step explanation:

The first term of this geometric sequence, a(1), is 1, and the common ratio, r, is 4.  Each new term is 4 times the previous term.  Thus,

a(n) = 1*4^(n - 1), and

a(11) = 4^10 = 1048576

The original value of a car is $18,000, and it depreciates (loses value) by 15% each year. What is the value of the car after th
Sliva [168]
A reduction of 15% per year means 100-15=85% reducing factor.
1st year: 0.85×18000=$15300.
2nd year: 0.85×15300=$13005.
3rd year: 0.85×13005=$11054.25.
So after 3 years the value of the car is $11054.25 or $11054 to the nearest dollar.
