Halfway Between 50 and 640

When you ask "What number is halfway between 50 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=50 and Y=640.

Halfway Between Line

To find the number halfway between 50 and 640, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 50 and 640 into our formula, we get:

(50 + 640)/2 = 345

Thus, the number halfway between 50 and 640 is 345.

To check that our answer is correct, we subtract 50 from 345 and subtract 345 from 640 and compare the two numbers:

345 - 50 = 295
640 - 345 = 295

As you can see, the halfway number is 295 higher than 50 and 295 lower than 640. Therefore, our halfway between answer of 345 above is correct.
