Halfway Between 45 and 521

When you ask "What number is halfway between 45 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=45 and Y=521.

Halfway Between Line

To find the number halfway between 45 and 521, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 45 and 521 into our formula, we get:

(45 + 521)/2 = 283

Thus, the number halfway between 45 and 521 is 283.

To check that our answer is correct, we subtract 45 from 283 and subtract 283 from 521 and compare the two numbers:

283 - 45 = 238
521 - 283 = 238

As you can see, the halfway number is 238 higher than 45 and 238 lower than 521. Therefore, our halfway between answer of 283 above is correct.
