Halfway Between 100 and 538

When you ask "What number is halfway between 100 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=100 and Y=538.

Halfway Between Line

To find the number halfway between 100 and 538, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 538 into our formula, we get:

(100 + 538)/2 = 319

Thus, the number halfway between 100 and 538 is 319.

To check that our answer is correct, we subtract 100 from 319 and subtract 319 from 538 and compare the two numbers:

319 - 100 = 219
538 - 319 = 219

As you can see, the halfway number is 219 higher than 100 and 219 lower than 538. Therefore, our halfway between answer of 319 above is correct.
