Halfway Between 8 and 644

When you ask "What number is halfway between 8 and 644?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=8 and Y=644.

Halfway Between Line

To find the number halfway between 8 and 644, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 8 and 644 into our formula, we get:

(8 + 644)/2 = 326

Thus, the number halfway between 8 and 644 is 326.

To check that our answer is correct, we subtract 8 from 326 and subtract 326 from 644 and compare the two numbers:

326 - 8 = 318
644 - 326 = 318

As you can see, the halfway number is 318 higher than 8 and 318 lower than 644. Therefore, our halfway between answer of 326 above is correct.
