Halfway Between 80 and 289

When you ask "What number is halfway between 80 and 289?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=80 and Y=289.

Halfway Between Line

To find the number halfway between 80 and 289, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 80 and 289 into our formula, we get:

(80 + 289)/2 = 184.5

Thus, the number halfway between 80 and 289 is 184.5.

To check that our answer is correct, we subtract 80 from 184.5 and subtract 184.5 from 289 and compare the two numbers:

184.5 - 80 = 104.5
289 - 184.5 = 104.5

As you can see, the halfway number is 104.5 higher than 80 and 104.5 lower than 289. Therefore, our halfway between answer of 184.5 above is correct.
