Halfway Between 55 and 631

When you ask "What number is halfway between 55 and 631?" 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=631.

Halfway Between Line

To find the number halfway between 55 and 631, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 55 and 631 into our formula, we get:

(55 + 631)/2 = 343

Thus, the number halfway between 55 and 631 is 343.

To check that our answer is correct, we subtract 55 from 343 and subtract 343 from 631 and compare the two numbers:

343 - 55 = 288
631 - 343 = 288

As you can see, the halfway number is 288 higher than 55 and 288 lower than 631. Therefore, our halfway between answer of 343 above is correct.
