Halfway Between 15 and 54

When you ask "What number is halfway between 15 and 54?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=15 and Y=54.

Halfway Between Line

To find the number halfway between 15 and 54, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 15 and 54 into our formula, we get:

(15 + 54)/2 = 34.5

Thus, the number halfway between 15 and 54 is 34.5.

To check that our answer is correct, we subtract 15 from 34.5 and subtract 34.5 from 54 and compare the two numbers:

34.5 - 15 = 19.5
54 - 34.5 = 19.5

As you can see, the halfway number is 19.5 higher than 15 and 19.5 lower than 54. Therefore, our halfway between answer of 34.5 above is correct.
