Halfway Between 100 and 297

When you ask "What number is halfway between 100 and 297?" 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=297.

Halfway Between Line

To find the number halfway between 100 and 297, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 297 into our formula, we get:

(100 + 297)/2 = 198.5

Thus, the number halfway between 100 and 297 is 198.5.

To check that our answer is correct, we subtract 100 from 198.5 and subtract 198.5 from 297 and compare the two numbers:

198.5 - 100 = 98.5
297 - 198.5 = 98.5

As you can see, the halfway number is 98.5 higher than 100 and 98.5 lower than 297. Therefore, our halfway between answer of 198.5 above is correct.
