Halfway Between 26 and 640

When you ask "What number is halfway between 26 and 640?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=26 and Y=640.

Halfway Between Line

To find the number halfway between 26 and 640, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 26 and 640 into our formula, we get:

(26 + 640)/2 = 333

Thus, the number halfway between 26 and 640 is 333.

To check that our answer is correct, we subtract 26 from 333 and subtract 333 from 640 and compare the two numbers:

333 - 26 = 307
640 - 333 = 307

As you can see, the halfway number is 307 higher than 26 and 307 lower than 640. Therefore, our halfway between answer of 333 above is correct.
