The average is 10... 11+11+9+7+12=50... 50/5=10
the average of 7,9,11,12,16 is = (7+9+11+12+16)/5 =11
5+7+9+12+12 = 45 and 45/5 = 9 which is the mean average
7 + 9 + 11 = 27. Divide by 3. = 9.

A house cat should weigh between 9 and 11 pounds on average.
(18 + 18 + 11 + 7 + 6 + 11 + 10 + 20 + 7)/9= 12========The mean, also often called the "average", is1/9 of (18 + 18 + 11 + 7 + 6 + 11 + 10 + 20 + 7)
(7+9+17)/3= 11
Average = (12 + 8 + 7)/3 = 27/3 = 9
18 9 11 14 7 9 12 the series is like 18/2= 9 9+2=11 11+3=14 14/2=7 7+2=9 9+3=12 so next number will be.. 12/2=6 then 6+2=8 8+3=11
The average or mean of 3, 5, 7, 9, and 11 is 7.
