Halfway Between 11 and 641

When you ask "What number is halfway between 11 and 641?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=11 and Y=641.

Halfway Between Line

To find the number halfway between 11 and 641, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 11 and 641 into our formula, we get:

(11 + 641)/2 = 326

Thus, the number halfway between 11 and 641 is 326.

To check that our answer is correct, we subtract 11 from 326 and subtract 326 from 641 and compare the two numbers:

326 - 11 = 315
641 - 326 = 315

As you can see, the halfway number is 315 higher than 11 and 315 lower than 641. Therefore, our halfway between answer of 326 above is correct.
