Halfway Between 85 and 405

When you ask "What number is halfway between 85 and 405?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=85 and Y=405.

Halfway Between Line

To find the number halfway between 85 and 405, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 85 and 405 into our formula, we get:

(85 + 405)/2 = 245

Thus, the number halfway between 85 and 405 is 245.

To check that our answer is correct, we subtract 85 from 245 and subtract 245 from 405 and compare the two numbers:

245 - 85 = 160
405 - 245 = 160

As you can see, the halfway number is 160 higher than 85 and 160 lower than 405. Therefore, our halfway between answer of 245 above is correct.
