Answer:

first 8 multiples of 6 = 6 12 18 24 30 36 42 48

mean \:  =  \frac{sum \: of \: observations}{number \: of \: observations}  \\ mean \:  =  \frac{6 + 12 + 18 + 24 + 30 + 36 + 42 + 48}{8}  =  \\  mean=  \frac{216}{8}  =27

Answer:

54

Step-by-step explanation:

(6+12+18+24+30+36+42+48)/8=54

if you know the sum of numbers 1-8 you can do it more quickly

sum of numbers 1-8=72

so after taking 6 common from all it will look like this

6(1+2+3+4+5+6+7+8)/8

you know that 1+2+3+4+5+6+7+8=72

so, (6 x 72)/8

= 6 x 9

= 54

I hope this helps you
