Halfway Between 35 and 309

When you ask "What number is halfway between 35 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=35 and Y=309.

Halfway Between Line

To find the number halfway between 35 and 309, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 35 and 309 into our formula, we get:

(35 + 309)/2 = 172

Thus, the number halfway between 35 and 309 is 172.

To check that our answer is correct, we subtract 35 from 172 and subtract 172 from 309 and compare the two numbers:

172 - 35 = 137
309 - 172 = 137

As you can see, the halfway number is 137 higher than 35 and 137 lower than 309. Therefore, our halfway between answer of 172 above is correct.
