Halfway Between 15 and 275

When you ask "What number is halfway between 15 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=15 and Y=275.

Halfway Between Line

To find the number halfway between 15 and 275, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 15 and 275 into our formula, we get:

(15 + 275)/2 = 145

Thus, the number halfway between 15 and 275 is 145.

To check that our answer is correct, we subtract 15 from 145 and subtract 145 from 275 and compare the two numbers:

145 - 15 = 130
275 - 145 = 130

As you can see, the halfway number is 130 higher than 15 and 130 lower than 275. Therefore, our halfway between answer of 145 above is correct.
