Halfway Between 90 and 200

When you ask "What number is halfway between 90 and 200?" 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=200.

Halfway Between Line

To find the number halfway between 90 and 200, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 90 and 200 into our formula, we get:

(90 + 200)/2 = 145

Thus, the number halfway between 90 and 200 is 145.

To check that our answer is correct, we subtract 90 from 145 and subtract 145 from 200 and compare the two numbers:

145 - 90 = 55
200 - 145 = 55

As you can see, the halfway number is 55 higher than 90 and 55 lower than 200. Therefore, our halfway between answer of 145 above is correct.
