Halfway Between 40 and 338

When you ask "What number is halfway between 40 and 338?" 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=338.

Halfway Between Line

To find the number halfway between 40 and 338, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 40 and 338 into our formula, we get:

(40 + 338)/2 = 189

Thus, the number halfway between 40 and 338 is 189.

To check that our answer is correct, we subtract 40 from 189 and subtract 189 from 338 and compare the two numbers:

189 - 40 = 149
338 - 189 = 149

As you can see, the halfway number is 149 higher than 40 and 149 lower than 338. Therefore, our halfway between answer of 189 above is correct.
