Halfway Between 31 and 669

When you ask "What number is halfway between 31 and 669?" 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=669.

Halfway Between Line

To find the number halfway between 31 and 669, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 31 and 669 into our formula, we get:

(31 + 669)/2 = 350

Thus, the number halfway between 31 and 669 is 350.

To check that our answer is correct, we subtract 31 from 350 and subtract 350 from 669 and compare the two numbers:

350 - 31 = 319
669 - 350 = 319

As you can see, the halfway number is 319 higher than 31 and 319 lower than 669. Therefore, our halfway between answer of 350 above is correct.
