Find the mean of $x, x + 2, x + 4, x + 6, x + 8$.

Given:

Given observations are $x, x + 2, x + 4, x + 6, x + 8$.

To do:

We have to find the mean of $x, x + 2, x + 4, x + 6, x + 8$.

Solution:

We know that,

Mean $=\frac{Sum\ of\ the\ observations}{Number\ of\ observations}$

Therefore,

Mean $=\frac{x + (x + 2)+ (x + 4) +(x + 6) + (x + 8)}{5}$

$=\frac{5x+20}{5}$

$=\frac{5(x+4)}{5}$

$=x+4$

Hence, the mean of the given observations is $x+4$.
