Halfway Between 100 and 676

When you ask "What number is halfway between 100 and 676?" 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=676.

Halfway Between Line

To find the number halfway between 100 and 676, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 676 into our formula, we get:

(100 + 676)/2 = 388

Thus, the number halfway between 100 and 676 is 388.

To check that our answer is correct, we subtract 100 from 388 and subtract 388 from 676 and compare the two numbers:

388 - 100 = 288
676 - 388 = 288

As you can see, the halfway number is 288 higher than 100 and 288 lower than 676. Therefore, our halfway between answer of 388 above is correct.
