The first 100 natural numbers are 1,2,3,...,100 is 50.5.
An average is a single number chosen to represent a group of numbers; it is typically the sum of the numbers divided by the number of numbers in the group. The average of the numbers 2, 3, 4, 7, and 9 is, for instance, 5.
We know that the sum of the first n natural numbers is = 2n(n+1)
Therefore, the sum of the first 100 natural numbers is = 2×100(101)
=200(101)=20200
Hence, the sum of the first 100 natural numbers is = 20200 = 101
200
Hence, the average of the first 100 natural numbers is = 101 = 50.5
