Halfway Between 25 and 557

When you ask "What number is halfway between 25 and 557?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=25 and Y=557.

Halfway Between Line

To find the number halfway between 25 and 557, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 25 and 557 into our formula, we get:

(25 + 557)/2 = 291

Thus, the number halfway between 25 and 557 is 291.

To check that our answer is correct, we subtract 25 from 291 and subtract 291 from 557 and compare the two numbers:

291 - 25 = 266
557 - 291 = 266

As you can see, the halfway number is 266 higher than 25 and 266 lower than 557. Therefore, our halfway between answer of 291 above is correct.
