To determine

To find: the geometric mean of the given two numbers

Answer to Problem 1CT

The geometric mean between the two given numbers is $10$

Explanation of Solution

Given Information: Two numbers 5 and 20.

Formula Used:

The geometric mean between two numbers a and b is defined by the relation,

  $c=\sqrt{ab}$

Calculation:

For the numbers 5 and 20,the geometric mean can be calculated using the given formula as,

  $\begin{array}{c}c=\sqrt{5\times 20}\\ =\sqrt{100}\\ =10\end{array}$
