Halfway Between 45 and 689

When you ask "What number is halfway between 45 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=45 and Y=689.

Halfway Between Line

To find the number halfway between 45 and 689, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 45 and 689 into our formula, we get:

(45 + 689)/2 = 367

Thus, the number halfway between 45 and 689 is 367.

To check that our answer is correct, we subtract 45 from 367 and subtract 367 from 689 and compare the two numbers:

367 - 45 = 322
689 - 367 = 322

As you can see, the halfway number is 322 higher than 45 and 322 lower than 689. Therefore, our halfway between answer of 367 above is correct.
