Halfway Between 55 and 403

When you ask "What number is halfway between 55 and 403?" 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=403.

Halfway Between Line

To find the number halfway between 55 and 403, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 55 and 403 into our formula, we get:

(55 + 403)/2 = 229

Thus, the number halfway between 55 and 403 is 229.

To check that our answer is correct, we subtract 55 from 229 and subtract 229 from 403 and compare the two numbers:

229 - 55 = 174
403 - 229 = 174

As you can see, the halfway number is 174 higher than 55 and 174 lower than 403. Therefore, our halfway between answer of 229 above is correct.
