Halfway Between 100 and 775

When you ask "What number is halfway between 100 and 775?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=100 and Y=775.

Halfway Between Line

To find the number halfway between 100 and 775, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 775 into our formula, we get:

(100 + 775)/2 = 437.5

Thus, the number halfway between 100 and 775 is 437.5.

To check that our answer is correct, we subtract 100 from 437.5 and subtract 437.5 from 775 and compare the two numbers:

437.5 - 100 = 337.5
775 - 437.5 = 337.5

As you can see, the halfway number is 337.5 higher than 100 and 337.5 lower than 775. Therefore, our halfway between answer of 437.5 above is correct.
