Solution

To find the third number, you can follow these steps:

  1. First, you need to find the total sum of the three numbers. Since the average is 20, you multiply this by 3 (because there are three numbers). 20 * 3 = 60.

  2. Then, you subtract the two given numbers from this total. 60 - 16 - 22 = 22.

So, the third number is 22.
