Include the following in your answer:

• Which one of the basic functions (linear, quadratic, rational, or exponential) is related to the arithmetic sequence?
• Which one of the basic functions (linear, quadratic, rational, or exponential) is related to the geometric sequence?
• Give at least two real-life examples of a sequences or series. One example should be arithmetic, and the second should be geometric. Explain how these examples would affect you personally.
