Halfway Between 78 and 253

When you ask "What number is halfway between 78 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=78 and Y=253.

Halfway Between Line

To find the number halfway between 78 and 253, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 78 and 253 into our formula, we get:

(78 + 253)/2 = 165.5

Thus, the number halfway between 78 and 253 is 165.5.

To check that our answer is correct, we subtract 78 from 165.5 and subtract 165.5 from 253 and compare the two numbers:

165.5 - 78 = 87.5
253 - 165.5 = 87.5

As you can see, the halfway number is 87.5 higher than 78 and 87.5 lower than 253. Therefore, our halfway between answer of 165.5 above is correct.
