Find the mean of the first 7 even whole numbers.

$\underline{ \underline{ \textbf{ \textsf{ᴀɴsᴡᴇʀ⟱}}}}$

Different values of x are :

=> 0 , 2 , 4 , 6 , 8 , 10 , 12.

$\sf \therefore \sum x = 0 + 2 + 4 + 6 + 8 + 10 + 12 \\ \sf \implies \: 56$

And,

No. of observations (n) = 7

$\sf \therefore mean \: ( \bar x) = \dfrac{ \sum x}{n} \\ \\ \sf \implies \: \frac{ \cancel{42} \: ^{6} }{ \cancel{7} \: ^{1} } = \boxed{ \sf{ \red{ \: 6 \: \: \: ans...}}}$
