The geometric mean of 3 and 75 is 15.0
The geometric mean of 3 an 48 is 12 [√(3 x 48) = √144 = 12]
The geometric mean of 3 and 27 is 9.0
3mean is the average, so 2 + 4 = 6; 6 / 2 = 3* * * * *The above is the arithmetic mean which is NOT the same thing as the geometric mean.The geometric mean of n non-negative numbers is the nth root of their product.So GM(2, 4) = sqrt(8) = 2.828 (approx).
It is 11.6190, approx.
