Halfway Between 90 and 251

When you ask "What number is halfway between 90 and 251?" 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=251.

Halfway Between Line

To find the number halfway between 90 and 251, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 90 and 251 into our formula, we get:

(90 + 251)/2 = 170.5

Thus, the number halfway between 90 and 251 is 170.5.

To check that our answer is correct, we subtract 90 from 170.5 and subtract 170.5 from 251 and compare the two numbers:

170.5 - 90 = 80.5
251 - 170.5 = 80.5

As you can see, the halfway number is 80.5 higher than 90 and 80.5 lower than 251. Therefore, our halfway between answer of 170.5 above is correct.
