Halfway Between 47 and 390

When you ask "What number is halfway between 47 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=47 and Y=390.

Halfway Between Line

To find the number halfway between 47 and 390, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 47 and 390 into our formula, we get:

(47 + 390)/2 = 218.5

Thus, the number halfway between 47 and 390 is 218.5.

To check that our answer is correct, we subtract 47 from 218.5 and subtract 218.5 from 390 and compare the two numbers:

218.5 - 47 = 171.5
390 - 218.5 = 171.5

As you can see, the halfway number is 171.5 higher than 47 and 171.5 lower than 390. Therefore, our halfway between answer of 218.5 above is correct.
