• Arithmetic Mean

$\star{ \pink{ \underline{ \underline{Ｓｏｌｕｔｉｏｎ : - }}}}$

We know that ➥

$\boxed{ \boxed{ \red{ \sf{Arithmetic \: Mean = \frac{sum \: of \: observation}{total \: number \: of \: observation}}}}}$

$\implies{Arithmetic \: Mean = \frac{ 1 + 2 + 3 + 4 + 5}{5}}$

$\implies{Arithmetic \: Mean = \cancel\frac{ 15}{5}} \\ \\ = 3$
