Halfway Between 45 and 290

When you ask "What number is halfway between 45 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=45 and Y=290.

Halfway Between Line

To find the number halfway between 45 and 290, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 45 and 290 into our formula, we get:

(45 + 290)/2 = 167.5

Thus, the number halfway between 45 and 290 is 167.5.

To check that our answer is correct, we subtract 45 from 167.5 and subtract 167.5 from 290 and compare the two numbers:

167.5 - 45 = 122.5
290 - 167.5 = 122.5

As you can see, the halfway number is 122.5 higher than 45 and 122.5 lower than 290. Therefore, our halfway between answer of 167.5 above is correct.
