## Falling_In_Katt one year ago If √6 is the geometric mean between 4 and another number, then the number is: A. 1.5 B. 9 C. 24

You already know what the geometric mean proportion is from the previous problem. You also know that if x is the geometric mean of a and b, then $$x = \sqrt{ab}$$ In this problem, you are given x and a. Plug them in the equation above and solve for b.
