Halfway Between 90 and 215

When you ask "What number is halfway between 90 and 215?" 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=215.

Halfway Between Line

To find the number halfway between 90 and 215, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 90 and 215 into our formula, we get:

(90 + 215)/2 = 152.5

Thus, the number halfway between 90 and 215 is 152.5.

To check that our answer is correct, we subtract 90 from 152.5 and subtract 152.5 from 215 and compare the two numbers:

152.5 - 90 = 62.5
215 - 152.5 = 62.5

As you can see, the halfway number is 62.5 higher than 90 and 62.5 lower than 215. Therefore, our halfway between answer of 152.5 above is correct.
