Halfway Between 65 and 331

When you ask "What number is halfway between 65 and 331?" 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=331.

Halfway Between Line

To find the number halfway between 65 and 331, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 65 and 331 into our formula, we get:

(65 + 331)/2 = 198

Thus, the number halfway between 65 and 331 is 198.

To check that our answer is correct, we subtract 65 from 198 and subtract 198 from 331 and compare the two numbers:

198 - 65 = 133
331 - 198 = 133

As you can see, the halfway number is 133 higher than 65 and 133 lower than 331. Therefore, our halfway between answer of 198 above is correct.
