Question

find
mean
of first 10 natural numbers
​

Answer 1

Answer:

The first 10 natural numbers are 1,2,3,4,5,6,7,8,9,10.

$mean = \frac{sum \: of \: observations}{number \: of \: observations}$

here number of observations = 10

$mean = \frac{1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10}{10} \\ mean = \frac{55}{10} \\ mean = \frac{11}{2} = 5.5$

The mean of first 10 natural numbers is 5.5.

I hope it is helpful.
