so this one all you need is to add up all the numbers together and devide them by how many numbers you have a good example is 1,17, 9, 21 if you add them up youll get 48 and since there is 4 numbers you devide that by 4 and get 12 which is your mean so you try this one out and ill help you see if you got the correct answer or not
