Halfway Between 90 and 204

When you ask "What number is halfway between 90 and 204?" 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=204.

Halfway Between Line

To find the number halfway between 90 and 204, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 90 and 204 into our formula, we get:

(90 + 204)/2 = 147

Thus, the number halfway between 90 and 204 is 147.

To check that our answer is correct, we subtract 90 from 147 and subtract 147 from 204 and compare the two numbers:

147 - 90 = 57
204 - 147 = 57

As you can see, the halfway number is 57 higher than 90 and 57 lower than 204. Therefore, our halfway between answer of 147 above is correct.
