Find the mean of first six multiple of 3

Answered by admin @


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
