Question

the arithmetic mean of first ten even natural numbers is ______​

Answer 1

Answer:

Mean =

sum of observations /no of observations

first ten even natural numbers are

= 2 ,4,6,8,10,12,14,16,18,20

= (2+4+6+8+10+12+14+16+18+20)/10

=110/10

= 11

Arithmetic mean of 1st ten even natural numbers is 11

Answer 2

Answer:

11

Step-by-step explanation:

Formula to find arthimetic mean :

Sum of observations/ no. of observations.

First ten even natural no.'s = 2,4,6,8,10,12,14,16,18,20.

Arithmetic mean of first 10 natural numbers = (2+4+6+8+10+12+14+16+18+20)/10

= 110/10

= 11

So, mean of first 10 even natural numbers is 11.
