Halfway Between 5 and 12

When you ask "What number is halfway between 5 and 12?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=5 and Y=12.

Halfway Between Line

To find the number halfway between 5 and 12, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 5 and 12 into our formula, we get:

(5 + 12)/2 = 8.5

Thus, the number halfway between 5 and 12 is 8.5.

To check that our answer is correct, we subtract 5 from 8.5 and subtract 8.5 from 12 and compare the two numbers:

8.5 - 5 = 3.5
12 - 8.5 = 3.5

As you can see, the halfway number is 3.5 higher than 5 and 3.5 lower than 12. Therefore, our halfway between answer of 8.5 above is correct.
