Adding all the numbers and dividing it by the total number of numbers.
For eg to get average of 3,2,10,5,3,7
We need to add up all those numbers i.e 3+2+10+5+3+7 = 30
Then divide it by 6 (as there are 6 numbers) so 30/6 which is 5.
So 5 is the average of 3,2,10,5,3,7.
Hope it helps and pls mark it as the best answer. :-)
