Halfway Between 9 and 691

When you ask "What number is halfway between 9 and 691?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=9 and Y=691.

Halfway Between Line

To find the number halfway between 9 and 691, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 9 and 691 into our formula, we get:

(9 + 691)/2 = 350

Thus, the number halfway between 9 and 691 is 350.

To check that our answer is correct, we subtract 9 from 350 and subtract 350 from 691 and compare the two numbers:

350 - 9 = 341
691 - 350 = 341

As you can see, the halfway number is 341 higher than 9 and 341 lower than 691. Therefore, our halfway between answer of 350 above is correct.
