Halfway Between 71 and 428

When you ask "What number is halfway between 71 and 428?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=71 and Y=428.

Halfway Between Line

To find the number halfway between 71 and 428, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 71 and 428 into our formula, we get:

(71 + 428)/2 = 249.5

Thus, the number halfway between 71 and 428 is 249.5.

To check that our answer is correct, we subtract 71 from 249.5 and subtract 249.5 from 428 and compare the two numbers:

249.5 - 71 = 178.5
428 - 249.5 = 178.5

As you can see, the halfway number is 178.5 higher than 71 and 178.5 lower than 428. Therefore, our halfway between answer of 249.5 above is correct.
