Halfway Between 90 and 529

When you ask "What number is halfway between 90 and 529?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=90 and Y=529.

Halfway Between Line

To find the number halfway between 90 and 529, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 90 and 529 into our formula, we get:

(90 + 529)/2 = 309.5

Thus, the number halfway between 90 and 529 is 309.5.

To check that our answer is correct, we subtract 90 from 309.5 and subtract 309.5 from 529 and compare the two numbers:

309.5 - 90 = 219.5
529 - 309.5 = 219.5

As you can see, the halfway number is 219.5 higher than 90 and 219.5 lower than 529. Therefore, our halfway between answer of 309.5 above is correct.
