Suppose you buy the car of your dreams. Research the price of your car. At the end of n years, the value of your car is given by the sequence vn = (Dream car Price)(3/4)n, n = 1, 2, 3, ..... Find the fifth term and explain what this value represents. Describe the nth term of the sequence in terms of the value of your car at the end of each year.
Given any sequence, how can you determine if it is an arithmetic sequence? Provide an example in your explanation.
Suppose you are provided with a geometric sequence. How can you find the sum of n terms of the sequence without having to add all of the terms? Provide an example in your explanation.
