Halfway Between 12 and 51

When you ask "What number is halfway between 12 and 51?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=12 and Y=51.

Halfway Between Line

To find the number halfway between 12 and 51, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 12 and 51 into our formula, we get:

(12 + 51)/2 = 31.5

Thus, the number halfway between 12 and 51 is 31.5.

To check that our answer is correct, we subtract 12 from 31.5 and subtract 31.5 from 51 and compare the two numbers:

31.5 - 12 = 19.5
51 - 31.5 = 19.5

As you can see, the halfway number is 19.5 higher than 12 and 19.5 lower than 51. Therefore, our halfway between answer of 31.5 above is correct.
