Geometric and arithmetic rate of return. Suppose you have the following rates of return: r = 0.1, r2 = 0.05, and T3 = 0.2. What are the geometric and arithmetic rates of return? Give an example (two periods) where the arithmetic rate of return is zero, and the geometric rate is negative. Give an example two periods) where the arithmetic rate of return is zero, and the geometric rate is -100%
