Halfway Between 85 and 730

When you ask "What number is halfway between 85 and 730?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=85 and Y=730.

Halfway Between Line

To find the number halfway between 85 and 730, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 85 and 730 into our formula, we get:

(85 + 730)/2 = 407.5

Thus, the number halfway between 85 and 730 is 407.5.

To check that our answer is correct, we subtract 85 from 407.5 and subtract 407.5 from 730 and compare the two numbers:

407.5 - 85 = 322.5
730 - 407.5 = 322.5

As you can see, the halfway number is 322.5 higher than 85 and 322.5 lower than 730. Therefore, our halfway between answer of 407.5 above is correct.
