Halfway Between 84 and 518

When you ask "What number is halfway between 84 and 518?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=84 and Y=518.

Halfway Between Line

To find the number halfway between 84 and 518, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 84 and 518 into our formula, we get:

(84 + 518)/2 = 301

Thus, the number halfway between 84 and 518 is 301.

To check that our answer is correct, we subtract 84 from 301 and subtract 301 from 518 and compare the two numbers:

301 - 84 = 217
518 - 301 = 217

As you can see, the halfway number is 217 higher than 84 and 217 lower than 518. Therefore, our halfway between answer of 301 above is correct.
