Halfway Between 75 and 423

When you ask "What number is halfway between 75 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=75 and Y=423.

Halfway Between Line

To find the number halfway between 75 and 423, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 75 and 423 into our formula, we get:

(75 + 423)/2 = 249

Thus, the number halfway between 75 and 423 is 249.

To check that our answer is correct, we subtract 75 from 249 and subtract 249 from 423 and compare the two numbers:

249 - 75 = 174
423 - 249 = 174

As you can see, the halfway number is 174 higher than 75 and 174 lower than 423. Therefore, our halfway between answer of 249 above is correct.
