Halfway Between 55 and 421

When you ask "What number is halfway between 55 and 421?" 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=421.

Halfway Between Line

To find the number halfway between 55 and 421, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 55 and 421 into our formula, we get:

(55 + 421)/2 = 238

Thus, the number halfway between 55 and 421 is 238.

To check that our answer is correct, we subtract 55 from 238 and subtract 238 from 421 and compare the two numbers:

238 - 55 = 183
421 - 238 = 183

As you can see, the halfway number is 183 higher than 55 and 183 lower than 421. Therefore, our halfway between answer of 238 above is correct.
