The mean of a set of numbers is the sum of the numbers over the count of the set (the number of values).
We have a set of four numbers and the mean is 5. We can see that the sum of the values is 20:
20 4 = 5
We have another set of three numbers whose mean is 12. We can write that as:
36 3 = 12
To find the mean of the seven numbers together, we can add the values together and divide by 7:
20 + 36 7 = 56 7 = 8 20 + 36 7 = 56 7 = 8
