Halfway Between 90 and 630

When you ask "What number is halfway between 90 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=90 and Y=630.

Halfway Between Line

To find the number halfway between 90 and 630, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 90 and 630 into our formula, we get:

(90 + 630)/2 = 360

Thus, the number halfway between 90 and 630 is 360.

To check that our answer is correct, we subtract 90 from 360 and subtract 360 from 630 and compare the two numbers:

360 - 90 = 270
630 - 360 = 270

As you can see, the halfway number is 270 higher than 90 and 270 lower than 630. Therefore, our halfway between answer of 360 above is correct.
