Halfway Between 65 and 518

When you ask "What number is halfway between 65 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=65 and Y=518.

Halfway Between Line

To find the number halfway between 65 and 518, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 65 and 518 into our formula, we get:

(65 + 518)/2 = 291.5

Thus, the number halfway between 65 and 518 is 291.5.

To check that our answer is correct, we subtract 65 from 291.5 and subtract 291.5 from 518 and compare the two numbers:

291.5 - 65 = 226.5
518 - 291.5 = 226.5

As you can see, the halfway number is 226.5 higher than 65 and 226.5 lower than 518. Therefore, our halfway between answer of 291.5 above is correct.
