Halfway Between 90 and 320

When you ask "What number is halfway between 90 and 320?" 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=320.

Halfway Between Line

To find the number halfway between 90 and 320, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 90 and 320 into our formula, we get:

(90 + 320)/2 = 205

Thus, the number halfway between 90 and 320 is 205.

To check that our answer is correct, we subtract 90 from 205 and subtract 205 from 320 and compare the two numbers:

205 - 90 = 115
320 - 205 = 115

As you can see, the halfway number is 115 higher than 90 and 115 lower than 320. Therefore, our halfway between answer of 205 above is correct.
