Halfway Between 100 and 785

When you ask "What number is halfway between 100 and 785?" 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=785.

Halfway Between Line

To find the number halfway between 100 and 785, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 785 into our formula, we get:

(100 + 785)/2 = 442.5

Thus, the number halfway between 100 and 785 is 442.5.

To check that our answer is correct, we subtract 100 from 442.5 and subtract 442.5 from 785 and compare the two numbers:

442.5 - 100 = 342.5
785 - 442.5 = 342.5

As you can see, the halfway number is 342.5 higher than 100 and 342.5 lower than 785. Therefore, our halfway between answer of 442.5 above is correct.
