**Find the geometric mean of the two numbers. 9 and 16**

**Answer:**

To find the GEOMETRIC MEAN between 2 given numbers, I can relate it to the arithmetic mean. To get the arithmetic mean (the average) of two numbers, you ADD the numbers and divide that answer by 2. To find the GEOMETRIC MEAN between 2 given numbers, you MULTIPLY the 2 numbers together and TAKE THE SQUARE ROOT of that answer. So, the geometric mean between 9 and 16 is found by multiplying them together to get 144, and then taking the square root of 144 to get 12. The answer is 12.
