Halfway Between 100 and 259

When you ask "What number is halfway between 100 and 259?" 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=259.

Halfway Between Line

To find the number halfway between 100 and 259, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 259 into our formula, we get:

(100 + 259)/2 = 179.5

Thus, the number halfway between 100 and 259 is 179.5.

To check that our answer is correct, we subtract 100 from 179.5 and subtract 179.5 from 259 and compare the two numbers:

179.5 - 100 = 79.5
259 - 179.5 = 79.5

As you can see, the halfway number is 79.5 higher than 100 and 79.5 lower than 259. Therefore, our halfway between answer of 179.5 above is correct.
