Halfway Between 25 and 666

When you ask "What number is halfway between 25 and 666?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=25 and Y=666.

Halfway Between Line

To find the number halfway between 25 and 666, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 25 and 666 into our formula, we get:

(25 + 666)/2 = 345.5

Thus, the number halfway between 25 and 666 is 345.5.

To check that our answer is correct, we subtract 25 from 345.5 and subtract 345.5 from 666 and compare the two numbers:

345.5 - 25 = 320.5
666 - 345.5 = 320.5

As you can see, the halfway number is 320.5 higher than 25 and 320.5 lower than 666. Therefore, our halfway between answer of 345.5 above is correct.
