Halfway Between 25 and 521

When you ask "What number is halfway between 25 and 521?" 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=521.

Halfway Between Line

To find the number halfway between 25 and 521, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 25 and 521 into our formula, we get:

(25 + 521)/2 = 273

Thus, the number halfway between 25 and 521 is 273.

To check that our answer is correct, we subtract 25 from 273 and subtract 273 from 521 and compare the two numbers:

273 - 25 = 248
521 - 273 = 248

As you can see, the halfway number is 248 higher than 25 and 248 lower than 521. Therefore, our halfway between answer of 273 above is correct.
