Halfway Between 55 and 458

When you ask "What number is halfway between 55 and 458?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=55 and Y=458.

Halfway Between Line

To find the number halfway between 55 and 458, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 55 and 458 into our formula, we get:

(55 + 458)/2 = 256.5

Thus, the number halfway between 55 and 458 is 256.5.

To check that our answer is correct, we subtract 55 from 256.5 and subtract 256.5 from 458 and compare the two numbers:

256.5 - 55 = 201.5
458 - 256.5 = 201.5

As you can see, the halfway number is 201.5 higher than 55 and 201.5 lower than 458. Therefore, our halfway between answer of 256.5 above is correct.
