Mean = (sum of the n numbers)/n
Mean = Total of the numbers / n So total of the numbers = n*mean
The sum of the first n natural numbers is n*(n+1)/2 There are n numbers so their mean = (n+1)/2
The sum from 1 to n is n*(n+1)/2In this case that mean 20*21/2 = 210The sum from 1 to n is n*(n+1)/2In this case that mean 20*21/2 = 210The sum from 1 to n is n*(n+1)/2In this case that mean 20*21/2 = 210The sum from 1 to n is n*(n+1)/2In this case that mean 20*21/2 = 210
