Halfway Between 89 and 507

When you ask "What number is halfway between 89 and 507?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=89 and Y=507.

Halfway Between Line

To find the number halfway between 89 and 507, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 89 and 507 into our formula, we get:

(89 + 507)/2 = 298

Thus, the number halfway between 89 and 507 is 298.

To check that our answer is correct, we subtract 89 from 298 and subtract 298 from 507 and compare the two numbers:

298 - 89 = 209
507 - 298 = 209

As you can see, the halfway number is 209 higher than 89 and 209 lower than 507. Therefore, our halfway between answer of 298 above is correct.
