QUESTION :-

mean of first 5 natural numbers

ANSWER :-

We will begin by writing the first five natural numbers, which are 1,2,3,4 and 5. Calculate the sum of these numbers. Then find the mean of the first five natural numbers using the formula, Average=Sum of observationsNumber of observationsAverage=Sum of observationsNumber of observations

Complete step-by-step answer:

Natural numbers are the numbers that help in counting.

For example, the numbers 1,2,3,4,….. are natural numbers.

Hence, the first five natural numbers are 1,2,3,4 and 5.

We have to find the mean of the first five natural numbers.

The mean is calculated by dividing the sum of observations by the number of observations.

We will find the sum of observations by adding all the first five natural numbers.

1+2+3+4+5=151+2+3+4+5=15

We will divide this by the number of observations, that is by 5

15/5=3

Hence, the mean of the first five natural numbers is 3.
