Halfway Between 25 and 309

When you ask "What number is halfway between 25 and 309?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=25 and Y=309.

Halfway Between Line

To find the number halfway between 25 and 309, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 25 and 309 into our formula, we get:

(25 + 309)/2 = 167

Thus, the number halfway between 25 and 309 is 167.

To check that our answer is correct, we subtract 25 from 167 and subtract 167 from 309 and compare the two numbers:

167 - 25 = 142
309 - 167 = 142

As you can see, the halfway number is 142 higher than 25 and 142 lower than 309. Therefore, our halfway between answer of 167 above is correct.
