Halfway Between 5 and 630

When you ask "What number is halfway between 5 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=5 and Y=630.

Halfway Between Line

To find the number halfway between 5 and 630, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 5 and 630 into our formula, we get:

(5 + 630)/2 = 317.5

Thus, the number halfway between 5 and 630 is 317.5.

To check that our answer is correct, we subtract 5 from 317.5 and subtract 317.5 from 630 and compare the two numbers:

317.5 - 5 = 312.5
630 - 317.5 = 312.5

As you can see, the halfway number is 312.5 higher than 5 and 312.5 lower than 630. Therefore, our halfway between answer of 317.5 above is correct.
