Halfway Between 40 and 278

When you ask "What number is halfway between 40 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=40 and Y=278.

Halfway Between Line

To find the number halfway between 40 and 278, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 40 and 278 into our formula, we get:

(40 + 278)/2 = 159

Thus, the number halfway between 40 and 278 is 159.

To check that our answer is correct, we subtract 40 from 159 and subtract 159 from 278 and compare the two numbers:

159 - 40 = 119
278 - 159 = 119

As you can see, the halfway number is 119 higher than 40 and 119 lower than 278. Therefore, our halfway between answer of 159 above is correct.
