Halfway Between 5 and 639

When you ask "What number is halfway between 5 and 639?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=5 and Y=639.

Halfway Between Line

To find the number halfway between 5 and 639, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 5 and 639 into our formula, we get:

(5 + 639)/2 = 322

Thus, the number halfway between 5 and 639 is 322.

To check that our answer is correct, we subtract 5 from 322 and subtract 322 from 639 and compare the two numbers:

322 - 5 = 317
639 - 322 = 317

As you can see, the halfway number is 317 higher than 5 and 317 lower than 639. Therefore, our halfway between answer of 322 above is correct.
