Halfway Between 70 and 630

When you ask "What number is halfway between 70 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=70 and Y=630.

Halfway Between Line

To find the number halfway between 70 and 630, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 70 and 630 into our formula, we get:

(70 + 630)/2 = 350

Thus, the number halfway between 70 and 630 is 350.

To check that our answer is correct, we subtract 70 from 350 and subtract 350 from 630 and compare the two numbers:

350 - 70 = 280
630 - 350 = 280

As you can see, the halfway number is 280 higher than 70 and 280 lower than 630. Therefore, our halfway between answer of 350 above is correct.
