Hen (11 + - 4) / 2 = 7/2 = 3.5 is the halfway point.
Here is the number line
-4,-3,-2,-1,0,1,2,3,(3.5)4,5,6,7,8,9,10,11
Notirce there are 8 1/2 places from either end to the mid point.
3.5
It is 15
41.5
It is 13
The number 8 is halfway between 5 and 11. It is 3 more than 5 and 3 less than 11. To find a halfway point (which is also the average), add the numbers together and divide by 2.
It is (10.7 + 11)/2 = 10.85
11.. 7+4=11 and 15-4=11
The average of -7 and 4 is -1.5 .
