Halfway Between 43 and 639

When you ask "What number is halfway between 43 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=43 and Y=639.

Halfway Between Line

To find the number halfway between 43 and 639, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 43 and 639 into our formula, we get:

(43 + 639)/2 = 341

Thus, the number halfway between 43 and 639 is 341.

To check that our answer is correct, we subtract 43 from 341 and subtract 341 from 639 and compare the two numbers:

341 - 43 = 298
639 - 341 = 298

As you can see, the halfway number is 298 higher than 43 and 298 lower than 639. Therefore, our halfway between answer of 341 above is correct.
