Halfway Between 15 and 319

When you ask "What number is halfway between 15 and 319?" 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=319.

Halfway Between Line

To find the number halfway between 15 and 319, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 15 and 319 into our formula, we get:

(15 + 319)/2 = 167

Thus, the number halfway between 15 and 319 is 167.

To check that our answer is correct, we subtract 15 from 167 and subtract 167 from 319 and compare the two numbers:

167 - 15 = 152
319 - 167 = 152

As you can see, the halfway number is 152 higher than 15 and 152 lower than 319. Therefore, our halfway between answer of 167 above is correct.
