Halfway Between 88 and 550

When you ask "What number is halfway between 88 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=88 and Y=550.

Halfway Between Line

To find the number halfway between 88 and 550, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 88 and 550 into our formula, we get:

(88 + 550)/2 = 319

Thus, the number halfway between 88 and 550 is 319.

To check that our answer is correct, we subtract 88 from 319 and subtract 319 from 550 and compare the two numbers:

319 - 88 = 231
550 - 319 = 231

As you can see, the halfway number is 231 higher than 88 and 231 lower than 550. Therefore, our halfway between answer of 319 above is correct.
