Halfway Between 17 and 689

When you ask "What number is halfway between 17 and 689?" 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=689.

Halfway Between Line

To find the number halfway between 17 and 689, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 17 and 689 into our formula, we get:

(17 + 689)/2 = 353

Thus, the number halfway between 17 and 689 is 353.

To check that our answer is correct, we subtract 17 from 353 and subtract 353 from 689 and compare the two numbers:

353 - 17 = 336
689 - 353 = 336

As you can see, the halfway number is 336 higher than 17 and 336 lower than 689. Therefore, our halfway between answer of 353 above is correct.
