Halfway Between 13 and 617

When you ask "What number is halfway between 13 and 617?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=13 and Y=617.

Halfway Between Line

To find the number halfway between 13 and 617, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 13 and 617 into our formula, we get:

(13 + 617)/2 = 315

Thus, the number halfway between 13 and 617 is 315.

To check that our answer is correct, we subtract 13 from 315 and subtract 315 from 617 and compare the two numbers:

315 - 13 = 302
617 - 315 = 302

As you can see, the halfway number is 302 higher than 13 and 302 lower than 617. Therefore, our halfway between answer of 315 above is correct.
