The ____________________ mean of n returns (or growth rates)is the appropriate mean to calculate if you wish to estimate the mean rate of return (or growth rate)for any single period in the future.

Geometric Mean

The nth root of the product of n numbers, useful for finding average rates of change in multiplicative processes.

Growth Rates

The percentage change of a specific variable over a certain period of time, often used to express the increase in size or value.
