Halfway Between 98 and 678

When you ask "What number is halfway between 98 and 678?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=98 and Y=678.

Halfway Between Line

To find the number halfway between 98 and 678, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 98 and 678 into our formula, we get:

(98 + 678)/2 = 388

Thus, the number halfway between 98 and 678 is 388.

To check that our answer is correct, we subtract 98 from 388 and subtract 388 from 678 and compare the two numbers:

388 - 98 = 290
678 - 388 = 290

As you can see, the halfway number is 290 higher than 98 and 290 lower than 678. Therefore, our halfway between answer of 388 above is correct.
