Find the mean of first ten even natural numbers.

Question:

Find the mean of first ten even natural numbers.

Solution:

The first five even natural numbers are 2 , 4 , 6 , 8 , 10 , 12 , 14 , 16 , 18 , 20

$\therefore$ Mean $=\frac{\text { Sum of numbers }}{\text { Total numbers }}$

$=\frac{2+4+6+8+10+12+14+16+18+20}{10}=11$

Mean = 11
