Halfway Between 36 and 309

When you ask "What number is halfway between 36 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=36 and Y=309.

Halfway Between Line

To find the number halfway between 36 and 309, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 36 and 309 into our formula, we get:

(36 + 309)/2 = 172.5

Thus, the number halfway between 36 and 309 is 172.5.

To check that our answer is correct, we subtract 36 from 172.5 and subtract 172.5 from 309 and compare the two numbers:

172.5 - 36 = 136.5
309 - 172.5 = 136.5

As you can see, the halfway number is 136.5 higher than 36 and 136.5 lower than 309. Therefore, our halfway between answer of 172.5 above is correct.
