Halfway Between 28 and 278

When you ask "What number is halfway between 28 and 278?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=28 and Y=278.

Halfway Between Line

To find the number halfway between 28 and 278, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 28 and 278 into our formula, we get:

(28 + 278)/2 = 153

Thus, the number halfway between 28 and 278 is 153.

To check that our answer is correct, we subtract 28 from 153 and subtract 153 from 278 and compare the two numbers:

153 - 28 = 125
278 - 153 = 125

As you can see, the halfway number is 125 higher than 28 and 125 lower than 278. Therefore, our halfway between answer of 153 above is correct.
