Halfway Between 88 and 390

When you ask "What number is halfway between 88 and 390?" 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=390.

Halfway Between Line

To find the number halfway between 88 and 390, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 88 and 390 into our formula, we get:

(88 + 390)/2 = 239

Thus, the number halfway between 88 and 390 is 239.

To check that our answer is correct, we subtract 88 from 239 and subtract 239 from 390 and compare the two numbers:

239 - 88 = 151
390 - 239 = 151

As you can see, the halfway number is 151 higher than 88 and 151 lower than 390. Therefore, our halfway between answer of 239 above is correct.
