What is the arithmetic average return over the 10-year period? b. What is the geometric average return over the 10-year period? c. If you invested $100 at the beginning, how much would you have at the end? a. What is the arithmetic average return over the 10-year period? The arithmetic average return over the 10-year period is 8.09 %. (Round to two decimal places.) b. What is the geometric average return over the 10-year period? To find the geometric average return, use the following formulas. First find the future value of investing $1 today, using the following formula: FV=$1x ((1+R) *(1+R2) ***(1+RT)) Then use the following formula and solve for R: FV=$1*(1 + R) 10 The geometric average return, R. over the 10-year period is %. (Round to four decimal places.)
