Halfway Between 11 and 243

When you ask "What number is halfway between 11 and 243?" 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=243.

Halfway Between Line

To find the number halfway between 11 and 243, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 11 and 243 into our formula, we get:

(11 + 243)/2 = 127

Thus, the number halfway between 11 and 243 is 127.

To check that our answer is correct, we subtract 11 from 127 and subtract 127 from 243 and compare the two numbers:

127 - 11 = 116
243 - 127 = 116

As you can see, the halfway number is 116 higher than 11 and 116 lower than 243. Therefore, our halfway between answer of 127 above is correct.
