Halfway Between 65 and 309

When you ask "What number is halfway between 65 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=65 and Y=309.

Halfway Between Line

To find the number halfway between 65 and 309, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 65 and 309 into our formula, we get:

(65 + 309)/2 = 187

Thus, the number halfway between 65 and 309 is 187.

To check that our answer is correct, we subtract 65 from 187 and subtract 187 from 309 and compare the two numbers:

187 - 65 = 122
309 - 187 = 122

As you can see, the halfway number is 122 higher than 65 and 122 lower than 309. Therefore, our halfway between answer of 187 above is correct.
