Halfway Between 40 and 578

When you ask "What number is halfway between 40 and 578?" 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=578.

Halfway Between Line

To find the number halfway between 40 and 578, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 40 and 578 into our formula, we get:

(40 + 578)/2 = 309

Thus, the number halfway between 40 and 578 is 309.

To check that our answer is correct, we subtract 40 from 309 and subtract 309 from 578 and compare the two numbers:

309 - 40 = 269
578 - 309 = 269

As you can see, the halfway number is 269 higher than 40 and 269 lower than 578. Therefore, our halfway between answer of 309 above is correct.
