government interest rate. Rd = 1.3% + 8.95% = 10.25% c) Did you use arithmetic or geometric averages to measure rates of return? The arithmetic mean is a simple average of the rates of return for each year. The geometric mean is based on compounding and is generally less than the arithmetic mean. Investors tend to use arithmetic means in forming their expectations of future returns; therefore we have chosen to use the arithmetic average. 2.

this assignment I would like to talk about arithmetic sequences and geometric sequences and want to give an example each how to calculate with those sequences. First I want to give a short definition of each sequence. “An arithmetic sequence is a sequence of numbers in which each succeeding term differs from the preceding term by the same amount. This amount is known as the common difference.” (Bluman‚ A. G. 2500‚ page 221) An example for an arithmetic sequence is: 1‚ 3‚ 5‚ 7‚ 9‚ 11‚ … (The common

In this week’s assignment I will attempt complete exercises 35 and 37 in the “Real World Applications” section on page 280 of Mathematics in Our World. For each exercise‚ specify whether it involves an arithmetic sequence or a geometric sequence and use the proper formulas where applicable. I will try to format my math work as shown in the “week one assignment guide” provided to us and try to be concise in my reasoning. Exercise 35: A person hired to build a CB Radio tower.
