Halfway Between 40 and 617

When you ask "What number is halfway between 40 and 617?" 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=617.

Halfway Between Line

To find the number halfway between 40 and 617, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 40 and 617 into our formula, we get:

(40 + 617)/2 = 328.5

Thus, the number halfway between 40 and 617 is 328.5.

To check that our answer is correct, we subtract 40 from 328.5 and subtract 328.5 from 617 and compare the two numbers:

328.5 - 40 = 288.5
617 - 328.5 = 288.5

As you can see, the halfway number is 288.5 higher than 40 and 288.5 lower than 617. Therefore, our halfway between answer of 328.5 above is correct.
