Geometric mean of 5 and 15= √(5x15)=√75=5√3
What is the sum of the first 27 terms of the geometric sequence -3, 3, - 3, 3, . . . ?
6.7082
Just use the definition of geometric mean. Multiply all the numbers together, then take the square root. (In this case, it is the square, or second, root, because there are two numbers; for the geometric mean of three numbers, you take the cubic root, etc.)
The geometric mean of 5 and 15 is sqrt (5x15)= sqrt (75)= 5sqrt(3).
