Halfway Between 72 and 289

When you ask "What number is halfway between 72 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=72 and Y=289.

Halfway Between Line

To find the number halfway between 72 and 289, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 72 and 289 into our formula, we get:

(72 + 289)/2 = 180.5

Thus, the number halfway between 72 and 289 is 180.5.

To check that our answer is correct, we subtract 72 from 180.5 and subtract 180.5 from 289 and compare the two numbers:

180.5 - 72 = 108.5
289 - 180.5 = 108.5

As you can see, the halfway number is 108.5 higher than 72 and 108.5 lower than 289. Therefore, our halfway between answer of 180.5 above is correct.
