Question

Find the mean of first ten natural numbers?​

Answer 1

Answer:

1+2+3+4+5+6+7+8+9+10÷10=5.5

Answer 2

Mean means average..

it's formula is..

$mean = \frac{sum}{total \: no \: of \: observations}$

here total no. of observations is 10..

And an interesting fact is that we have a formula to calculate sum of first n natural numbers..

$= \frac{n(n + 1)}{2}$

You can try calculating number by number and check out with this formulae...

So let's get into the mean value

$mean = \frac{10(10 + 1)}{2} \times \frac{1}{10}$

as n=10

=110/20

=11/2

=5.5

hence your answer is 5.5..
