GM(4, 60) = sqrt(4*60) = 4*sqrt(15) = 15.492 approx
The geometric mean of 4 and 5 is 4.472135955
34.6410161514
What is the sum of the first 27 terms of the geometric sequence -3, 3, - 3, 3, . . . ?
No. Geometric mean of n numbers is the nth root of the product of the n numbers. → geometric mean of 4 and 9 is √(4×9) = √36 = 6.

geometric mean of 4 and 25=√(4x25)=√100=10
To find a geometric mean, we multiply all of the terms together and take the nth root of the result (where n is the number of terms we are averaging). With 10 and 6, we find the geometric mean is the square root of 10*6 = 60. Sqrt(60) = 2*sqrt(15).
The geometric mean of two numbers is the square root of their product. For example, the geometric mean of 4 and 25 is 10.
Arithmetic mean = (60+85)/2 = 145/2 = 72.5 Geometric mean = sqrt(60*85) = 71.41 approx.
