Halfway Between 40 and 507

When you ask "What number is halfway between 40 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=40 and Y=507.

Halfway Between Line

To find the number halfway between 40 and 507, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 40 and 507 into our formula, we get:

(40 + 507)/2 = 273.5

Thus, the number halfway between 40 and 507 is 273.5.

To check that our answer is correct, we subtract 40 from 273.5 and subtract 273.5 from 507 and compare the two numbers:

273.5 - 40 = 233.5
507 - 273.5 = 233.5

As you can see, the halfway number is 233.5 higher than 40 and 233.5 lower than 507. Therefore, our halfway between answer of 273.5 above is correct.
