Best Answer

The mean, or average, of a set of numbers is calculated by adding all the numbers together and then dividing by the total number of values. In this case, the sum of 1 + 2 + 3 + 4 is 10. Since there are 4 numbers in the set, the mean is 10 divided by 4, which equals 2.5. Therefore, the mean of 1, 2, 3, and 4 is 2.5.

Well, isn't that a lovely set of numbers you have there! To find the mean, you simply add up all the numbers and then divide by how many there are. So for 1, 2, 3, and 4, you would add them together to get 10, then divide by 4 to find the mean, which is 2.5. Just like painting a happy little tree, math can be quite soothing once you get the hang of it.

Oh, dude, the mean of 1, 2, 3, and 4 is like the average of those numbers. You just add them up and divide by how many there are. So, in this case, it's (1+2+3+4)/4, which equals 2.5. Easy peasy, lemon squeezy!

2.5 is the answer because 1+2+3+4 is 10 and 10/4 is 2.5
