Add the numbers then divide the sum by the number of numbers you added e.g. average of 1,2,3,4 four numbers add em up 1+2+3+4 =10 divide the sum by the number of numbers 10/4 average of 1,2,3,4 is 2.5
The average, in this case, is the sum divided by 4 (since there are 4 numbers).

It is a mathematical statement. It means that the average of a set of numbers is negative 10 and the sum of this average and four is, therefore, negative six!
The sum of the four numbers would be equal to 5 x 4 = 20.

the sum of all numbers is 6*4=24 sum of two = 2*2=4 average of other four=24-4/4=5
108/4 = 27

Average of five numbers is 82 so their sum is 82*5 = 410. Average of four of them is 80, so their sum is 80*4 = 320. So the fifth number is 410 - 320 = 90.
The mean average of a set of numbers is the sum of the numbers divided by how many of them there are. If there are 8 numbers with a sum of 2464, their mean average is 2464 ÷ 8 = 308.
The sum of the first four prime numbers is 17.
