Halfway Between 5 and 278

When you ask "What number is halfway between 5 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=5 and Y=278.

Halfway Between Line

To find the number halfway between 5 and 278, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 5 and 278 into our formula, we get:

(5 + 278)/2 = 141.5

Thus, the number halfway between 5 and 278 is 141.5.

To check that our answer is correct, we subtract 5 from 141.5 and subtract 141.5 from 278 and compare the two numbers:

141.5 - 5 = 136.5
278 - 141.5 = 136.5

As you can see, the halfway number is 136.5 higher than 5 and 136.5 lower than 278. Therefore, our halfway between answer of 141.5 above is correct.
