Halfway Between 5 and 390

When you ask "What number is halfway between 5 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=5 and Y=390.

Halfway Between Line

To find the number halfway between 5 and 390, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 5 and 390 into our formula, we get:

(5 + 390)/2 = 197.5

Thus, the number halfway between 5 and 390 is 197.5.

To check that our answer is correct, we subtract 5 from 197.5 and subtract 197.5 from 390 and compare the two numbers:

197.5 - 5 = 192.5
390 - 197.5 = 192.5

As you can see, the halfway number is 192.5 higher than 5 and 192.5 lower than 390. Therefore, our halfway between answer of 197.5 above is correct.
