Halfway Between 65 and 311

When you ask "What number is halfway between 65 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=65 and Y=311.

Halfway Between Line

To find the number halfway between 65 and 311, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 65 and 311 into our formula, we get:

(65 + 311)/2 = 188

Thus, the number halfway between 65 and 311 is 188.

To check that our answer is correct, we subtract 65 from 188 and subtract 188 from 311 and compare the two numbers:

188 - 65 = 123
311 - 188 = 123

As you can see, the halfway number is 123 higher than 65 and 123 lower than 311. Therefore, our halfway between answer of 188 above is correct.
