Question

Find the mean of first seven whole numbers.

Answer 1

First seven whole numbers are 0,1,2,3,4,5,6.

So mean = sum of observations/no of observations
(0+1+2+3+4+5+6)/7= 21/7
= 3
So required answer is 3.

Hope it will help you !!!

Answer 2

Given,

The first seven whole numbers.

To find,

The mean of the first seven whole numbers.

Solution,

The mean of the first seven whole numbers will be 3.

We can easily solve this problem by following the given steps.

According to the question,

We have the first seven whole numbers.

(Whole numbers are the numbers that start from 0 and can be counted till infinity. For example, 0,1,2,3,4, etc.)

The first seven rational numbers are 0,1,2,3,4,5 and 6.

We know that the formula to find the mean is given as follows:

Mean = Sum of all the observations/total number of observations

Mean = (0+1+2+3+4+5+6)/7

Mean = 21/7

Mean = 3

Hence, the mean of the first seven whole numbers is 3.
