Halfway Between 3 and 12

When you ask "What number is halfway between 3 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=3 and Y=12.

Halfway Between Line

To find the number halfway between 3 and 12, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 3 and 12 into our formula, we get:

(3 + 12)/2 = 7.5

Thus, the number halfway between 3 and 12 is 7.5.

To check that our answer is correct, we subtract 3 from 7.5 and subtract 7.5 from 12 and compare the two numbers:

7.5 - 3 = 4.5
12 - 7.5 = 4.5

As you can see, the halfway number is 4.5 higher than 3 and 4.5 lower than 12. Therefore, our halfway between answer of 7.5 above is correct.
