Add the 3 numbers together and divide that answer by 3. Example: The average of 2, 4, and 9. Average = (2+4+9)/3 = 15/3 =5.

If the average of 3 numbers is 37 then the sum of those numbers = 37 * 3 = 111. Which is an odd number. Adding together even numbers never results in an odd number. Therefore the 3 numbers can not be even numbers; consecutive or otherwise. The question can not be answered.
When one of the numbers is 0, you must count it to the numbers of data. For example, 1, 0, 3, and 8. To find the average, or the mean, add the four numbers together and divide their sum by 4. (1 + 0 + 3 + 8)/4= 12/4 = 3 The average is 3.
To find the median with two numbers, do as you would to find the "average" or the "mean" by finding the sum between the two numbers and dividing the sum (or total) by two.
The term average (which can also be referred to as the mean) is where you add all of the numbers in a set and divide by how many numbers there are. For example, the average of 2, 3, 5, and 6. First, add all of the numbers. 2+3 = 5 5+5 = 10 10+6 = 16 or... 2+3+5+6 = 16 Lastly, you divide by the amount of numbers in the set. In this example, there are four numbers. Now, you divide by the total by the amount of numbers. 16/4 This equals 4, and you have your average (or mean)!
