That would be the square root of 60, approximately 7.7. Because 3/7.7 is (close to) 7.7/60.
It is sqrt(20) = 4.4721, approx.
sqrt(6*10) = sqrt(60) = 7.75 (approx)
If you mean as a percentage then it is 20%
No, the geometric mean is not the same as the mean of two numbers.
The geometric mean of 10 and 20 is 14.1421356237
That would be the square root of 60, approximately 7.7. Because 3/7.7 is (close to) 7.7/60.
Geometric mean of 6 and 20 = sqrt(6*20) = sqrt(120) = 10.95445
What is the sum of the first 27 terms of the geometric sequence -3, 3, - 3, 3, . . . ?
Geometric mean = sqrt(5*80) = sqrt(400) = 20
it is 10

Geometric mean of two numbers is the square root of their product so sqrt(8*50) = sqrt(400) = 20
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).
Arithmetic mean = (60+85)/2 = 145/2 = 72.5 Geometric mean = sqrt(60*85) = 71.41 approx.
GM(4, 60) = sqrt(4*60) = 4*sqrt(15) = 15.492 approx
It is approx 16.73
