Halfway Between 4 and 278

When you ask "What number is halfway between 4 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=4 and Y=278.

Halfway Between Line

To find the number halfway between 4 and 278, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 4 and 278 into our formula, we get:

(4 + 278)/2 = 141

Thus, the number halfway between 4 and 278 is 141.

To check that our answer is correct, we subtract 4 from 141 and subtract 141 from 278 and compare the two numbers:

141 - 4 = 137
278 - 141 = 137

As you can see, the halfway number is 137 higher than 4 and 137 lower than 278. Therefore, our halfway between answer of 141 above is correct.
