Question

find the Arithmetic mean of first ten natural numbers

Answer 1

Arthematic mean =sum of 1st 10 natural numbers/ 10
=10 (10+1)/2/10
=55/10
=11/2
=5.5

Answer 2

Answer:

the arithmetic mean of first ten natural numbers is 5.5

Step-by-step explanation:

Mean is the sum of observation to the total number of observation.

We have to find the Arithmetic mean of first ten natural numbers

First 10 natural numbers are:

1, 2, 3, 4, 5, 6, 7, 8, 9, 10

Sum of observation = 1+2+3+4+5+6+7+8+9+10 =55

Total number of observation = 10

then;

by definition:

$\text{Arithmetic mean of first ten natural numbers}=\frac{55}{10} = 5.5$

Therefore, the Arithmetic mean of first ten natural numbers is 5.5
