Halfway Between 55 and 405

When you ask "What number is halfway between 55 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=55 and Y=405.

Halfway Between Line

To find the number halfway between 55 and 405, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 55 and 405 into our formula, we get:

(55 + 405)/2 = 230

Thus, the number halfway between 55 and 405 is 230.

To check that our answer is correct, we subtract 55 from 230 and subtract 230 from 405 and compare the two numbers:

230 - 55 = 175
405 - 230 = 175

As you can see, the halfway number is 175 higher than 55 and 175 lower than 405. Therefore, our halfway between answer of 230 above is correct.
