Halfway Between 100 and 622

When you ask "What number is halfway between 100 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=100 and Y=622.

Halfway Between Line

To find the number halfway between 100 and 622, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 622 into our formula, we get:

(100 + 622)/2 = 361

Thus, the number halfway between 100 and 622 is 361.

To check that our answer is correct, we subtract 100 from 361 and subtract 361 from 622 and compare the two numbers:

361 - 100 = 261
622 - 361 = 261

As you can see, the halfway number is 261 higher than 100 and 261 lower than 622. Therefore, our halfway between answer of 361 above is correct.
