Chat with our AI personalities
The sum of the first n natural numbers is n*(n+1)/2 There are n numbers so their mean = (n+1)/2
Mean = Total of the numbers / n So total of the numbers = n*mean
The average of n numbers = (sum of n numbers) / (count of n numbers).
Count the number of elements in the set - call this number n. Add up all the numbers in the set - call this total t Then mean = t/n
