If the mean of $11,14,p,26,10,12,18\And 6$ is$15$, find p

In question  given that,

$11,14,p,26,10,12,18\And 6$

Mean $=15$

We have to find the value for  p,

Whereas n is the total number

\[N=8\]

$\bar{x}=(x1+x2+..xn)/n$

$15=(11+14+p+26+10+12+18+6)/8$

$15*8=97+p$

$120=97+p$

$p=120-97$

$p=23$ Therefore,$23$is the value of p
