Halfway Between 40 and 538

When you ask "What number is halfway between 40 and 538?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=40 and Y=538.

Halfway Between Line

To find the number halfway between 40 and 538, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 40 and 538 into our formula, we get:

(40 + 538)/2 = 289

Thus, the number halfway between 40 and 538 is 289.

To check that our answer is correct, we subtract 40 from 289 and subtract 289 from 538 and compare the two numbers:

289 - 40 = 249
538 - 289 = 249

As you can see, the halfway number is 249 higher than 40 and 249 lower than 538. Therefore, our halfway between answer of 289 above is correct.
