Answer 2

Given:

Seven numbers 1, 2, 3, 4, 5, 6, 7.

To find:

The mean of given numbers.

Solution:

The mean of given numbers is 4.

To find the answer, we will follow the following steps:

First of all, we should know that the mean of 'n' numbers is equal to the sum of n numbers divided by total numbers i.e. n.

This means,

$mean \: = \frac{sum \: of \: n \: numbers}{n}$

Now,

As given, we have,

Numbers 1, 2, 3, 4, 5, 6, 7

Here,

total numbers or n = 7

The sum of all numbers

$= 1 + 2 + 3 + 4 + 5 + 6 + 7$

$= 28$

So, the mean of given numbers

$= \frac{28}{7}$

$= 4$

Hence, the mean of 1, 2, 3, 4, 5, 6, 7 is 4.
