The total of the 6 numbers is 48 (6x8) Adding another number will take the total to 7. So with an average of 10, the total of the 7 numbers will be 70 (7x10) 70 - 48 = 22 which is our seventh number.
It is not possible to find out the average of a number without knowing how many numbers were added together to get said number. If there were say, 7 numbers added together to get the total of 27.352, then you would divide 27.352 by 7 to get the average.
The mean of numbers is the average. To find this, first add all the numbers, then divide by how many numbers you added.
In total, we are changing the sum of the 9 numbers by 1 + 2 + ... + 9 = 9 x 10 / 2 = 45, so each of the numbers is increased by, on average, 45/9=5. If the old average was 40, the new one is 40 + <the average amount each number was increased by> = 40 + 5 = 45.
The mean of a set of data is also known as the average. To get the average, add all the numbers in a data set up, then take away the number of numbers. eg. data set = 5,6,7,6,6,4,4,3,4,5,4,6. Added = 60 Number of numbers = 12 60/12 = 5 = Average
Average can be solved by adding all of the numbers and dividing by the total number of items being added. So:14 + 15 + 16 = 45 / 3 numbers = 15

The sum of the first six numbers is (6 x 19) = 114The sum of the new group of seven numbers is (7 x 20) = 140The seventh number is (140 - 114) = 26.==========================================The seventh number contains enough material to make itself 20and also to raise each of the previous six numbers from 19 to 20.Therefore it must be [ 20 + (6 x 1) ] = (20 + 6) = 26.
45 will be the average...
add up all the numbers and then divide that number by the number of numbers that you added up.
It is not possible to find out the average of a number without knowing how many numbers were added together to get said number. If there were say, 7 numbers added together to get the total of 27.352, then you would divide 27.352 by 7 to get the average.

An average is found by adding all the relevant numbers together, and then dividing by the number of numbers added. This is a concept learned in elementary school.
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
mean means the average or all the numbers in the set added together and then divided by the number of numbers in the set of numbers.
