Halfway Between 11 and 307

When you ask "What number is halfway between 11 and 307?" 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=307.

Halfway Between Line

To find the number halfway between 11 and 307, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 11 and 307 into our formula, we get:

(11 + 307)/2 = 159

Thus, the number halfway between 11 and 307 is 159.

To check that our answer is correct, we subtract 11 from 159 and subtract 159 from 307 and compare the two numbers:

159 - 11 = 148
307 - 159 = 148

As you can see, the halfway number is 148 higher than 11 and 148 lower than 307. Therefore, our halfway between answer of 159 above is correct.
