When you ask "What number is halfway between 55 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=55 and Y=489.
To find the number halfway between 55 and 489, we use the following formula:
(X + Y)/2 = Halfway Between
When we enter 55 and 489 into our formula, we get:
(55 + 489)/2 = 272
Thus, the number halfway between 55 and 489 is 272.
To check that our answer is correct, we subtract 55 from 272 and subtract 272 from 489 and compare the two numbers:
272 - 55 = 217
489 - 272 = 217
As you can see, the halfway number is 217 higher than 55 and 217 lower than 489. Therefore, our halfway between answer of 272 above is correct.
