Halfway Between 25 and 405

When you ask "What number is halfway between 25 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=25 and Y=405.

Halfway Between Line

To find the number halfway between 25 and 405, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 25 and 405 into our formula, we get:

(25 + 405)/2 = 215

Thus, the number halfway between 25 and 405 is 215.

To check that our answer is correct, we subtract 25 from 215 and subtract 215 from 405 and compare the two numbers:

215 - 25 = 190
405 - 215 = 190

As you can see, the halfway number is 190 higher than 25 and 190 lower than 405. Therefore, our halfway between answer of 215 above is correct.
