Halfway Between 15 and 561

When you ask "What number is halfway between 15 and 561?" 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=561.

Halfway Between Line

To find the number halfway between 15 and 561, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 15 and 561 into our formula, we get:

(15 + 561)/2 = 288

Thus, the number halfway between 15 and 561 is 288.

To check that our answer is correct, we subtract 15 from 288 and subtract 288 from 561 and compare the two numbers:

288 - 15 = 273
561 - 288 = 273

As you can see, the halfway number is 273 higher than 15 and 273 lower than 561. Therefore, our halfway between answer of 288 above is correct.
