Halfway Between 98 and 642

When you ask "What number is halfway between 98 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=98 and Y=642.

Halfway Between Line

To find the number halfway between 98 and 642, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 98 and 642 into our formula, we get:

(98 + 642)/2 = 370

Thus, the number halfway between 98 and 642 is 370.

To check that our answer is correct, we subtract 98 from 370 and subtract 370 from 642 and compare the two numbers:

370 - 98 = 272
642 - 370 = 272

As you can see, the halfway number is 272 higher than 98 and 272 lower than 642. Therefore, our halfway between answer of 370 above is correct.
