Halfway Between 4 and 390

When you ask "What number is halfway between 4 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=4 and Y=390.

Halfway Between Line

To find the number halfway between 4 and 390, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 4 and 390 into our formula, we get:

(4 + 390)/2 = 197

Thus, the number halfway between 4 and 390 is 197.

To check that our answer is correct, we subtract 4 from 197 and subtract 197 from 390 and compare the two numbers:

197 - 4 = 193
390 - 197 = 193

As you can see, the halfway number is 193 higher than 4 and 193 lower than 390. Therefore, our halfway between answer of 197 above is correct.
