Halfway Between 78 and 275

When you ask "What number is halfway between 78 and 275?" 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=275.

Halfway Between Line

To find the number halfway between 78 and 275, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 78 and 275 into our formula, we get:

(78 + 275)/2 = 176.5

Thus, the number halfway between 78 and 275 is 176.5.

To check that our answer is correct, we subtract 78 from 176.5 and subtract 176.5 from 275 and compare the two numbers:

176.5 - 78 = 98.5
275 - 176.5 = 98.5

As you can see, the halfway number is 98.5 higher than 78 and 98.5 lower than 275. Therefore, our halfway between answer of 176.5 above is correct.
