Question

what is mean of 1,2,3,4,5,6,7 ? ​

Answer 1

$\large\bold\orange{\underline{Answer:-}}$

$\large\implies$ Sum of numbers = (1 + 2 + 3 + 4 + 5 + 6 + 7) = 28

$\large\implies$ Total numbers = 7

➻ Mean = $\large\frac{Sum \ of \ numbers}{Total \ numbers}$

➻ Mean = $\large\frac{28}{7}$

➻ Mean = $\boxed{\bold{\purple{4}}}$

Answer 2

Answer:

The mean of the data is 4

Step-by-step explanation:

Here we have been given to find the respective mean  of the following given data as below;

Data -  1,2,3,4,5,6,7

Now as we know that for finding the mean we have to find the average of the numbers by dividing the sum of these numbers by their total number of data.

Mean = Sum of all the number / total numbers

Here the sum of all the numbers = 1 +2 + 3+ 4+ 5+6+7

= 28

Total numbers = 7

Mean = $\frac{28}{7}$

= 4

Hence the mean of the data is 4
