Halfway Between 90 and 259

When you ask "What number is halfway between 90 and 259?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=90 and Y=259.

Halfway Between Line

To find the number halfway between 90 and 259, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 90 and 259 into our formula, we get:

(90 + 259)/2 = 174.5

Thus, the number halfway between 90 and 259 is 174.5.

To check that our answer is correct, we subtract 90 from 174.5 and subtract 174.5 from 259 and compare the two numbers:

174.5 - 90 = 84.5
259 - 174.5 = 84.5

As you can see, the halfway number is 84.5 higher than 90 and 84.5 lower than 259. Therefore, our halfway between answer of 174.5 above is correct.
