Halfway Between 15 and 605

When you ask "What number is halfway between 15 and 605?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=15 and Y=605.

Halfway Between Line

To find the number halfway between 15 and 605, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 15 and 605 into our formula, we get:

(15 + 605)/2 = 310

Thus, the number halfway between 15 and 605 is 310.

To check that our answer is correct, we subtract 15 from 310 and subtract 310 from 605 and compare the two numbers:

310 - 15 = 295
605 - 310 = 295

As you can see, the halfway number is 295 higher than 15 and 295 lower than 605. Therefore, our halfway between answer of 310 above is correct.
