Halfway Between 13 and 659

When you ask "What number is halfway between 13 and 659?" 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=659.

Halfway Between Line

To find the number halfway between 13 and 659, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 13 and 659 into our formula, we get:

(13 + 659)/2 = 336

Thus, the number halfway between 13 and 659 is 336.

To check that our answer is correct, we subtract 13 from 336 and subtract 336 from 659 and compare the two numbers:

336 - 13 = 323
659 - 336 = 323

As you can see, the halfway number is 323 higher than 13 and 323 lower than 659. Therefore, our halfway between answer of 336 above is correct.
