Halfway Between 36 and 640

When you ask "What number is halfway between 36 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=36 and Y=640.

Halfway Between Line

To find the number halfway between 36 and 640, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 36 and 640 into our formula, we get:

(36 + 640)/2 = 338

Thus, the number halfway between 36 and 640 is 338.

To check that our answer is correct, we subtract 36 from 338 and subtract 338 from 640 and compare the two numbers:

338 - 36 = 302
640 - 338 = 302

As you can see, the halfway number is 302 higher than 36 and 302 lower than 640. Therefore, our halfway between answer of 338 above is correct.
