Halfway Between 55 and 712

When you ask "What number is halfway between 55 and 712?" 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=712.

Halfway Between Line

To find the number halfway between 55 and 712, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 55 and 712 into our formula, we get:

(55 + 712)/2 = 383.5

Thus, the number halfway between 55 and 712 is 383.5.

To check that our answer is correct, we subtract 55 from 383.5 and subtract 383.5 from 712 and compare the two numbers:

383.5 - 55 = 328.5
712 - 383.5 = 328.5

As you can see, the halfway number is 328.5 higher than 55 and 328.5 lower than 712. Therefore, our halfway between answer of 383.5 above is correct.
