Halfway Between 51 and 507

When you ask "What number is halfway between 51 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=51 and Y=507.

Halfway Between Line

To find the number halfway between 51 and 507, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 51 and 507 into our formula, we get:

(51 + 507)/2 = 279

Thus, the number halfway between 51 and 507 is 279.

To check that our answer is correct, we subtract 51 from 279 and subtract 279 from 507 and compare the two numbers:

279 - 51 = 228
507 - 279 = 228

As you can see, the halfway number is 228 higher than 51 and 228 lower than 507. Therefore, our halfway between answer of 279 above is correct.
