Then as there are three numbers take the cube root.
The harmonic mean is one of the three Pythagorean meansFor all positive data sets containing at least one pair of nonequal values the harmonic mean is always the least of the three means while the arithmetic mean is always the greatest of the three and the geometric mean is always in between. As another example the geometric mean of the three numbers 4 1 and 132 is the cube root of their product 18 which is 12 that is 4 1 1 32 3 1 2. If you have 10000 and get paid 10 interest on that 10000 every year for 25 years the amount of interest is 1000 every year for 25 years or 25000. 3 4096 16.
