The geometric mean of n numbers (t{1}, t{2}, ..., t{n}) is given by (Π t{n})^(1/n)
→ geometric mean of 8.5 and 12.4 = (8.5 × 12.4)^(1/2) = 10.26645... ≈ 10.266
1.The Geometric mean is less then the arithmetic mean. GEOMETRIC MEAN < ARITHMETIC MEAN 2.
advantages of geometric mean
The difference between arithmetic and geometric mean you can find in the following link: "Calculation of the geometric mean of two numbers".
The geometric mean is 9.798 as the square root of 8 times 12. Scroll down to related links and look for more on "geometric mean".
The geometric mean of 4 and 5 is 4.472135955
Arithmetic mean = (60+85)/2 = 145/2 = 72.5 Geometric mean = sqrt(60*85) = 71.41 approx.
