Halfway Between 90 and 617

When you ask "What number is halfway between 90 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=90 and Y=617.

Halfway Between Line

To find the number halfway between 90 and 617, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 90 and 617 into our formula, we get:

(90 + 617)/2 = 353.5

Thus, the number halfway between 90 and 617 is 353.5.

To check that our answer is correct, we subtract 90 from 353.5 and subtract 353.5 from 617 and compare the two numbers:

353.5 - 90 = 263.5
617 - 353.5 = 263.5

As you can see, the halfway number is 263.5 higher than 90 and 263.5 lower than 617. Therefore, our halfway between answer of 353.5 above is correct.
