Halfway Between 55 and 551

When you ask "What number is halfway between 55 and 551?" 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=551.

Halfway Between Line

To find the number halfway between 55 and 551, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 55 and 551 into our formula, we get:

(55 + 551)/2 = 303

Thus, the number halfway between 55 and 551 is 303.

To check that our answer is correct, we subtract 55 from 303 and subtract 303 from 551 and compare the two numbers:

303 - 55 = 248
551 - 303 = 248

As you can see, the halfway number is 248 higher than 55 and 248 lower than 551. Therefore, our halfway between answer of 303 above is correct.
