The geometric mean of 3 and 75 is 15.0
The geometric mean of 3 and 27 is 9.0
The geometric mean of 3 an 48 is 12 [√(3 x 48) = √144 = 12]
It is 11.6190, approx.
If, by geometric number (?) you mean geometric mean, then the answer is 40.

What is the sum of the first 27 terms of the geometric sequence -3, 3, - 3, 3, . . . ?
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.)
