Halfway Between 88 and 622

When you ask "What number is halfway between 88 and 622?" 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=622.

Halfway Between Line

To find the number halfway between 88 and 622, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 88 and 622 into our formula, we get:

(88 + 622)/2 = 355

Thus, the number halfway between 88 and 622 is 355.

To check that our answer is correct, we subtract 88 from 355 and subtract 355 from 622 and compare the two numbers:

355 - 88 = 267
622 - 355 = 267

As you can see, the halfway number is 267 higher than 88 and 267 lower than 622. Therefore, our halfway between answer of 355 above is correct.
