To find the average we have to add all numbers together and divide that sum by number of numbers which we added. Lets do this 10+18+23=51 Lets divide it by number of numbers addes, so by 3 51:3=17 - its average of 10, 18 and 23
The average of the numbers 10, 18, and 23 is found by adding them together to get 51, and then dividing this sum by the number of values, which is 3. Thus, the average is 17.
