Halfway Between 88 and 642

When you ask "What number is halfway between 88 and 642?" 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=642.

Halfway Between Line

To find the number halfway between 88 and 642, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 88 and 642 into our formula, we get:

(88 + 642)/2 = 365

Thus, the number halfway between 88 and 642 is 365.

To check that our answer is correct, we subtract 88 from 365 and subtract 365 from 642 and compare the two numbers:

365 - 88 = 277
642 - 365 = 277

As you can see, the halfway number is 277 higher than 88 and 277 lower than 642. Therefore, our halfway between answer of 365 above is correct.
