Halfway Between 25 and 689

When you ask "What number is halfway between 25 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=25 and Y=689.

Halfway Between Line

To find the number halfway between 25 and 689, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 25 and 689 into our formula, we get:

(25 + 689)/2 = 357

Thus, the number halfway between 25 and 689 is 357.

To check that our answer is correct, we subtract 25 from 357 and subtract 357 from 689 and compare the two numbers:

357 - 25 = 332
689 - 357 = 332

As you can see, the halfway number is 332 higher than 25 and 332 lower than 689. Therefore, our halfway between answer of 357 above is correct.
