Halfway Between 89 and 505

When you ask "What number is halfway between 89 and 505?" 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=505.

Halfway Between Line

To find the number halfway between 89 and 505, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 89 and 505 into our formula, we get:

(89 + 505)/2 = 297

Thus, the number halfway between 89 and 505 is 297.

To check that our answer is correct, we subtract 89 from 297 and subtract 297 from 505 and compare the two numbers:

297 - 89 = 208
505 - 297 = 208

As you can see, the halfway number is 208 higher than 89 and 208 lower than 505. Therefore, our halfway between answer of 297 above is correct.
