Halfway Between 15 and 307

When you ask "What number is halfway between 15 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=15 and Y=307.

Halfway Between Line

To find the number halfway between 15 and 307, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 15 and 307 into our formula, we get:

(15 + 307)/2 = 161

Thus, the number halfway between 15 and 307 is 161.

To check that our answer is correct, we subtract 15 from 161 and subtract 161 from 307 and compare the two numbers:

161 - 15 = 146
307 - 161 = 146

As you can see, the halfway number is 146 higher than 15 and 146 lower than 307. Therefore, our halfway between answer of 161 above is correct.
