Halfway Between 72 and 290

When you ask "What number is halfway between 72 and 290?" 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=290.

Halfway Between Line

To find the number halfway between 72 and 290, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 72 and 290 into our formula, we get:

(72 + 290)/2 = 181

Thus, the number halfway between 72 and 290 is 181.

To check that our answer is correct, we subtract 72 from 181 and subtract 181 from 290 and compare the two numbers:

181 - 72 = 109
290 - 181 = 109

As you can see, the halfway number is 109 higher than 72 and 109 lower than 290. Therefore, our halfway between answer of 181 above is correct.
