Halfway Between 31 and 629

When you ask "What number is halfway between 31 and 629?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=31 and Y=629.

Halfway Between Line

To find the number halfway between 31 and 629, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 31 and 629 into our formula, we get:

(31 + 629)/2 = 330

Thus, the number halfway between 31 and 629 is 330.

To check that our answer is correct, we subtract 31 from 330 and subtract 330 from 629 and compare the two numbers:

330 - 31 = 299
629 - 330 = 299

As you can see, the halfway number is 299 higher than 31 and 299 lower than 629. Therefore, our halfway between answer of 330 above is correct.
