Halfway Between 67 and 309

When you ask "What number is halfway between 67 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=67 and Y=309.

Halfway Between Line

To find the number halfway between 67 and 309, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 67 and 309 into our formula, we get:

(67 + 309)/2 = 188

Thus, the number halfway between 67 and 309 is 188.

To check that our answer is correct, we subtract 67 from 188 and subtract 188 from 309 and compare the two numbers:

188 - 67 = 121
309 - 188 = 121

As you can see, the halfway number is 121 higher than 67 and 121 lower than 309. Therefore, our halfway between answer of 188 above is correct.
