Halfway Between 80 and 551

When you ask "What number is halfway between 80 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=80 and Y=551.

Halfway Between Line

To find the number halfway between 80 and 551, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 80 and 551 into our formula, we get:

(80 + 551)/2 = 315.5

Thus, the number halfway between 80 and 551 is 315.5.

To check that our answer is correct, we subtract 80 from 315.5 and subtract 315.5 from 551 and compare the two numbers:

315.5 - 80 = 235.5
551 - 315.5 = 235.5

As you can see, the halfway number is 235.5 higher than 80 and 235.5 lower than 551. Therefore, our halfway between answer of 315.5 above is correct.
