Halfway Between 10 and 390

When you ask "What number is halfway between 10 and 390?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=10 and Y=390.

Halfway Between Line

To find the number halfway between 10 and 390, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 10 and 390 into our formula, we get:

(10 + 390)/2 = 200

Thus, the number halfway between 10 and 390 is 200.

To check that our answer is correct, we subtract 10 from 200 and subtract 200 from 390 and compare the two numbers:

200 - 10 = 190
390 - 200 = 190

As you can see, the halfway number is 190 higher than 10 and 190 lower than 390. Therefore, our halfway between answer of 200 above is correct.
