What is the sum of the first 27 terms of the geometric sequence -3, 3, - 3, 3, . . . ?
The geometric mean of 5 and 15 is sqrt (5x15)= sqrt (75)= 5sqrt(3).
The geometric mean of 15 and 24 is 18.973665961
Geometric mean of 12 and 15 is 13.416407864998738 Look at link: "Calculation of the geometric mean of two numbers".
No, it is 12.
Geometric mean of 5 and 15= √(5x15)=√75=5√3
