Question

Find the mean of first 11 even natural numbers

Answer 1

Answer:

all even natural number 2,4,6,8,10,12,14,16,18,20,22

Step-by-step explanation:

average mean

2+4+6+8+10+12+14+16+18+20+22 upon 11

132 upon 11

=12

Answer 2

Given,

The first 11 even natural numbers

To Find,

The mean =?

Solution,

We can solve the question as follows:

It is given that we have to find the mean of the first 11 even natural numbers.

The first 11 natural numbers are 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22.

$First\: 11\: natural\: numbers = 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22$

Now,

The mean of a given set of observations is given as the sum of all observations divided by the total number of observations.

$Mean = \frac{Sum\: of\: all\: observations}{Total\: number\: of\: observations}$

Here,

$Sum\: of\: all\: observations = 2+ 4+ 6+8+10+12+14+ 16+18+20+22 = 132$

$Total\: observations = 11$

Therefore,

$Mean = \frac{132}{11}$

          $= 12$

Hence, the mean of the first 11 even natural numbers is 12.
