Halfway Between 17 and 489

When you ask "What number is halfway between 17 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=17 and Y=489.

Halfway Between Line

To find the number halfway between 17 and 489, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 17 and 489 into our formula, we get:

(17 + 489)/2 = 253

Thus, the number halfway between 17 and 489 is 253.

To check that our answer is correct, we subtract 17 from 253 and subtract 253 from 489 and compare the two numbers:

253 - 17 = 236
489 - 253 = 236

As you can see, the halfway number is 236 higher than 17 and 236 lower than 489. Therefore, our halfway between answer of 253 above is correct.
