Halfway Between 55 and 423

When you ask "What number is halfway between 55 and 423?" 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=423.

Halfway Between Line

To find the number halfway between 55 and 423, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 55 and 423 into our formula, we get:

(55 + 423)/2 = 239

Thus, the number halfway between 55 and 423 is 239.

To check that our answer is correct, we subtract 55 from 239 and subtract 239 from 423 and compare the two numbers:

239 - 55 = 184
423 - 239 = 184

As you can see, the halfway number is 184 higher than 55 and 184 lower than 423. Therefore, our halfway between answer of 239 above is correct.
