Halfway Between 99 and 773

When you ask "What number is halfway between 99 and 773?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=99 and Y=773.

Halfway Between Line

To find the number halfway between 99 and 773, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 99 and 773 into our formula, we get:

(99 + 773)/2 = 436

Thus, the number halfway between 99 and 773 is 436.

To check that our answer is correct, we subtract 99 from 436 and subtract 436 from 773 and compare the two numbers:

436 - 99 = 337
773 - 436 = 337

As you can see, the halfway number is 337 higher than 99 and 337 lower than 773. Therefore, our halfway between answer of 436 above is correct.
