Question

Find the mean of first ten natural numbers. I want full answer of this..Do some fastly ​

Answer 1

Step-by-step explanation:

Sum of first ten Natural numbers =

2

n(n+1)

, where n=10

=

2

10(11)

=55

Now Mean of first ten Natural number =

10

55

=5.5

Answer 2

Answer:-

First 10natual numbers are

• 1,2,3,4,5,6,7,8,9,10

We know that

$\boxed{\sf S_n=\dfrac{n(n+1)}{2}}$

• n=10

$\boxed{\sf\star Mean=\dfrac{Sum\:of\:terms}{Number\: of\:terms}}$

$\\ \sf\longmapsto Mean=\dfrac{\dfrac{n(n+1)}{2}}{10}$

$\\ \sf\longmapsto Mean=\dfrac{\dfrac{10(10+1)}{2}}{10}$

$\\ \sf\longmapsto Mean=\dfrac{\dfrac{10(11)}{2}}{10}$

$\\ \sf\longmapsto Mean=\dfrac{\dfrac{110}{2}}{10}$

$\\ \sf\longmapsto Mean=\dfrac{55}{10}$

$\\ \sf\longmapsto Mean=5.5$
