Halfway Between 55 and 689

When you ask "What number is halfway between 55 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=55 and Y=689.

Halfway Between Line

To find the number halfway between 55 and 689, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 55 and 689 into our formula, we get:

(55 + 689)/2 = 372

Thus, the number halfway between 55 and 689 is 372.

To check that our answer is correct, we subtract 55 from 372 and subtract 372 from 689 and compare the two numbers:

372 - 55 = 317
689 - 372 = 317

As you can see, the halfway number is 317 higher than 55 and 317 lower than 689. Therefore, our halfway between answer of 372 above is correct.
