Halfway Between 67 and 489

When you ask "What number is halfway between 67 and 489?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=67 and Y=489.

Halfway Between Line

To find the number halfway between 67 and 489, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 67 and 489 into our formula, we get:

(67 + 489)/2 = 278

Thus, the number halfway between 67 and 489 is 278.

To check that our answer is correct, we subtract 67 from 278 and subtract 278 from 489 and compare the two numbers:

278 - 67 = 211
489 - 278 = 211

As you can see, the halfway number is 211 higher than 67 and 211 lower than 489. Therefore, our halfway between answer of 278 above is correct.
