Halfway Between 55 and 345

When you ask "What number is halfway between 55 and 345?" 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=345.

Halfway Between Line

To find the number halfway between 55 and 345, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 55 and 345 into our formula, we get:

(55 + 345)/2 = 200

Thus, the number halfway between 55 and 345 is 200.

To check that our answer is correct, we subtract 55 from 200 and subtract 200 from 345 and compare the two numbers:

200 - 55 = 145
345 - 200 = 145

As you can see, the halfway number is 145 higher than 55 and 145 lower than 345. Therefore, our halfway between answer of 200 above is correct.
