Halfway Between 84 and 900

When you ask "What number is halfway between 84 and 900?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=84 and Y=900.

Halfway Between Line

To find the number halfway between 84 and 900, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 84 and 900 into our formula, we get:

(84 + 900)/2 = 492

Thus, the number halfway between 84 and 900 is 492.

To check that our answer is correct, we subtract 84 from 492 and subtract 492 from 900 and compare the two numbers:

492 - 84 = 408
900 - 492 = 408

As you can see, the halfway number is 408 higher than 84 and 408 lower than 900. Therefore, our halfway between answer of 492 above is correct.
