What is the sum of the first 27 terms of the geometric sequence -3, 3, - 3, 3, . . . ?
To find the ARITHMETIC mean of 4 and 10, you add them up and then divide by n number of values: (4+10)/2 = 7 To find the GEOMETRIC mean, you multiply 4 and 10, and then find the nth root: the square root of 40 is 6.32 (to 3 significant figures).
The geometric mean of 8 is: 8.0
Used the GEOMEAN function on Excel and the answer it gave was 20.
geometric mean of 6 and 30=√(6x30)=√180=6√5
The geometric mean of 10 and 12 is: 10.9544511501
The geometric mean of 10 and 20 is 14.1421356237
The geometric mean of two numbers is the square root of their product. In you instance any two factors of 900 will have a geometric mean of 30 eg 2 & 450 (2 x 15 = 30, 30 x 15 = 450); 3 & 300 (3 x 10 = 30, 30 x 10 = 300); 6 & 150 (6 x 5 = 30, 30 x 5 = 150) etc etc
The geometric mean of 18 and 30 is approximately 23. 2379 (√(18 x 30) = √540).
The geometric mean of any single number is itself!

The geometric mean of two numbers is the square root of their product, in this case GM = sqrt 90 or 3 root 10 = 9.487
geo. mean=√(30x4)=2√30 10.95445
sqrt(8*15) is the geometric mean. sqrt(120)=2*sqrt(30)
The geometric mean of two numbers is the square root of their product. For example, the geometric mean of 4 and 25 is 10.
