Halfway Between 11 and 275

When you ask "What number is halfway between 11 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=11 and Y=275.

Halfway Between Line

To find the number halfway between 11 and 275, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 11 and 275 into our formula, we get:

(11 + 275)/2 = 143

Thus, the number halfway between 11 and 275 is 143.

To check that our answer is correct, we subtract 11 from 143 and subtract 143 from 275 and compare the two numbers:

143 - 11 = 132
275 - 143 = 132

As you can see, the halfway number is 132 higher than 11 and 132 lower than 275. Therefore, our halfway between answer of 143 above is correct.
