Question

Find the mean of first six multiple of 3

Answer 1

Answer:

$mean = 10.5$

Step-by-step explanation:

3,6,9,12,15,18 are first three multiples of 3.

/* we know that ,

$mean =\frac{sum \: of \: the \: observations }{number \: of \: observations }$

$mean =\frac{3+6+9+12+15+18}{6}\\=\frac{63}{6}\\=\frac{21}{2}\\=10.5$

Therefore,

$mean = 10.5$
