Halfway Between 100 and 275

When you ask "What number is halfway between 100 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=100 and Y=275.

Halfway Between Line

To find the number halfway between 100 and 275, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 275 into our formula, we get:

(100 + 275)/2 = 187.5

Thus, the number halfway between 100 and 275 is 187.5.

To check that our answer is correct, we subtract 100 from 187.5 and subtract 187.5 from 275 and compare the two numbers:

187.5 - 100 = 87.5
275 - 187.5 = 87.5

As you can see, the halfway number is 87.5 higher than 100 and 87.5 lower than 275. Therefore, our halfway between answer of 187.5 above is correct.
