Halfway Between 2 and 278

When you ask "What number is halfway between 2 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=2 and Y=278.

Halfway Between Line

To find the number halfway between 2 and 278, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 2 and 278 into our formula, we get:

(2 + 278)/2 = 140

Thus, the number halfway between 2 and 278 is 140.

To check that our answer is correct, we subtract 2 from 140 and subtract 140 from 278 and compare the two numbers:

140 - 2 = 138
278 - 140 = 138

As you can see, the halfway number is 138 higher than 2 and 138 lower than 278. Therefore, our halfway between answer of 140 above is correct.
