Halfway Between 47 and 637

When you ask "What number is halfway between 47 and 637?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=47 and Y=637.

Halfway Between Line

To find the number halfway between 47 and 637, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 47 and 637 into our formula, we get:

(47 + 637)/2 = 342

Thus, the number halfway between 47 and 637 is 342.

To check that our answer is correct, we subtract 47 from 342 and subtract 342 from 637 and compare the two numbers:

342 - 47 = 295
637 - 342 = 295

As you can see, the halfway number is 295 higher than 47 and 295 lower than 637. Therefore, our halfway between answer of 342 above is correct.
