Halfway Between 55 and 431

When you ask "What number is halfway between 55 and 431?" 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=431.

Halfway Between Line

To find the number halfway between 55 and 431, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 55 and 431 into our formula, we get:

(55 + 431)/2 = 243

Thus, the number halfway between 55 and 431 is 243.

To check that our answer is correct, we subtract 55 from 243 and subtract 243 from 431 and compare the two numbers:

243 - 55 = 188
431 - 243 = 188

As you can see, the halfway number is 188 higher than 55 and 188 lower than 431. Therefore, our halfway between answer of 243 above is correct.
