Halfway Between 55 and 507

When you ask "What number is halfway between 55 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=55 and Y=507.

Halfway Between Line

To find the number halfway between 55 and 507, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 55 and 507 into our formula, we get:

(55 + 507)/2 = 281

Thus, the number halfway between 55 and 507 is 281.

To check that our answer is correct, we subtract 55 from 281 and subtract 281 from 507 and compare the two numbers:

281 - 55 = 226
507 - 281 = 226

As you can see, the halfway number is 226 higher than 55 and 226 lower than 507. Therefore, our halfway between answer of 281 above is correct.
