Halfway Between 100 and 253

When you ask "What number is halfway between 100 and 253?" 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=253.

Halfway Between Line

To find the number halfway between 100 and 253, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 253 into our formula, we get:

(100 + 253)/2 = 176.5

Thus, the number halfway between 100 and 253 is 176.5.

To check that our answer is correct, we subtract 100 from 176.5 and subtract 176.5 from 253 and compare the two numbers:

176.5 - 100 = 76.5
253 - 176.5 = 76.5

As you can see, the halfway number is 76.5 higher than 100 and 76.5 lower than 253. Therefore, our halfway between answer of 176.5 above is correct.
