Halfway Between 72 and 551

When you ask "What number is halfway between 72 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=72 and Y=551.

Halfway Between Line

To find the number halfway between 72 and 551, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 72 and 551 into our formula, we get:

(72 + 551)/2 = 311.5

Thus, the number halfway between 72 and 551 is 311.5.

To check that our answer is correct, we subtract 72 from 311.5 and subtract 311.5 from 551 and compare the two numbers:

311.5 - 72 = 239.5
551 - 311.5 = 239.5

As you can see, the halfway number is 239.5 higher than 72 and 239.5 lower than 551. Therefore, our halfway between answer of 311.5 above is correct.
