Question

what is the mean of 1,2,3,4,5,6,7​

Answer 1

$\huge{\underline{\underline{\huge{\bold{AnsweR \: :-}}}}}$

Mean = $\huge\frac{sum \: of \: the \: quantities}{number \: of \: quantities}$

Sum of the quantities = 1+2+3+4+5+6+7 = 28

Number of quantity = 7

Mean =

$\huge \frac{28}{7} = 4$

Therefore, Mean = 4

Answer 2

$\huge \fbox{Answer}$

$\large \underline{\underline{ \frak{ \color{red}Given::}}}$

${ \mapsto \sf{No. \: to \: find \: mean \: are \: 1,2,3,4,5,6 \: and \: 7.}}$

$\large \underline{\underline{ \frak{ \color{lime}To \: find::}}}$

${ \leadsto \sf{Find \: the \: mean \: of \: the \: given \: number. }}$

$\large \underline{\underline{ \frak{ \color{blue}Formula \: required::}}}$

$\pink{\star}{ \boxed {\rm{Mean \: of \: given \: number= \frac{Sum \: of \: given \: numbers}{Total \: numbers \: are \: given} }}} \pink{ \star}$

$\large \underline{\underline{ \frak{ \color{indigo}According \: to \: Question::}}}$

${ : :\implies{\sf{Mean \: of \: given \: number= \frac{Sum \: of \: given \: numbers}{Total \: numbers \: are \: given} }}}$

${ : :\implies{\sf{Mean \: of \: given \: number= \frac{1 + 2 + 3 + 4 + 5 + 6 + 7}{7} }}}$

${ : :\implies{\sf{Mean \: of \: given \: number= \frac{28}{7} }}}$

${ : :\implies{\sf{Mean \: of \: given \: number= 4}}}$

$\large {\underline{ \frak{ \color{indigo}Hence, }}}$

$\: \: \: \: \: \: \: \: \: \pink{ \star} \underline{ \fbox{\rm{Mean \: of \: given \: number= 4}}}$
