Halfway Between 40 and 630

When you ask "What number is halfway between 40 and 630?" 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=630.

Halfway Between Line

To find the number halfway between 40 and 630, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 40 and 630 into our formula, we get:

(40 + 630)/2 = 335

Thus, the number halfway between 40 and 630 is 335.

To check that our answer is correct, we subtract 40 from 335 and subtract 335 from 630 and compare the two numbers:

335 - 40 = 295
630 - 335 = 295

As you can see, the halfway number is 295 higher than 40 and 295 lower than 630. Therefore, our halfway between answer of 335 above is correct.
