Answer: B represents 7
This problem is asking us to find halfway between 2 and 12.
[Method One]
12 - 2 = 10
-
10 / 2 = 5
-
2 + 5 = 7
or
12 - 5 = 7
[Method Two]
[tex]\displaystyle \frac{2+12}{2} =\frac{14}{2} =7[/tex]
[Method Three]
We can count up from 2 and down from 12 until we hit the middle
2 12
3 11
4 10
5 9
6 8
7 7
