Halfway Between 17 and 615

When you ask "What number is halfway between 17 and 615?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=17 and Y=615.

Halfway Between Line

To find the number halfway between 17 and 615, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 17 and 615 into our formula, we get:

(17 + 615)/2 = 316

Thus, the number halfway between 17 and 615 is 316.

To check that our answer is correct, we subtract 17 from 316 and subtract 316 from 615 and compare the two numbers:

316 - 17 = 299
615 - 316 = 299

As you can see, the halfway number is 299 higher than 17 and 299 lower than 615. Therefore, our halfway between answer of 316 above is correct.
