Halfway Between 90 and 275

When you ask "What number is halfway between 90 and 275?" 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=275.

Halfway Between Line

To find the number halfway between 90 and 275, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 90 and 275 into our formula, we get:

(90 + 275)/2 = 182.5

Thus, the number halfway between 90 and 275 is 182.5.

To check that our answer is correct, we subtract 90 from 182.5 and subtract 182.5 from 275 and compare the two numbers:

182.5 - 90 = 92.5
275 - 182.5 = 92.5

As you can see, the halfway number is 92.5 higher than 90 and 92.5 lower than 275. Therefore, our halfway between answer of 182.5 above is correct.
