Halfway Between 67 and 311

When you ask "What number is halfway between 67 and 311?" 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=311.

Halfway Between Line

To find the number halfway between 67 and 311, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 67 and 311 into our formula, we get:

(67 + 311)/2 = 189

Thus, the number halfway between 67 and 311 is 189.

To check that our answer is correct, we subtract 67 from 189 and subtract 189 from 311 and compare the two numbers:

189 - 67 = 122
311 - 189 = 122

As you can see, the halfway number is 122 higher than 67 and 122 lower than 311. Therefore, our halfway between answer of 189 above is correct.
