Halfway Between 90 and 550

When you ask "What number is halfway between 90 and 550?" 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=550.

Halfway Between Line

To find the number halfway between 90 and 550, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 90 and 550 into our formula, we get:

(90 + 550)/2 = 320

Thus, the number halfway between 90 and 550 is 320.

To check that our answer is correct, we subtract 90 from 320 and subtract 320 from 550 and compare the two numbers:

320 - 90 = 230
550 - 320 = 230

As you can see, the halfway number is 230 higher than 90 and 230 lower than 550. Therefore, our halfway between answer of 320 above is correct.
