Halfway Between 80 and 290

When you ask "What number is halfway between 80 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=80 and Y=290.

Halfway Between Line

To find the number halfway between 80 and 290, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 80 and 290 into our formula, we get:

(80 + 290)/2 = 185

Thus, the number halfway between 80 and 290 is 185.

To check that our answer is correct, we subtract 80 from 185 and subtract 185 from 290 and compare the two numbers:

185 - 80 = 105
290 - 185 = 105

As you can see, the halfway number is 105 higher than 80 and 105 lower than 290. Therefore, our halfway between answer of 185 above is correct.
