Halfway Between 17 and 401

When you ask "What number is halfway between 17 and 401?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=17 and Y=401.

Halfway Between Line

To find the number halfway between 17 and 401, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 17 and 401 into our formula, we get:

(17 + 401)/2 = 209

Thus, the number halfway between 17 and 401 is 209.

To check that our answer is correct, we subtract 17 from 209 and subtract 209 from 401 and compare the two numbers:

209 - 17 = 192
401 - 209 = 192

As you can see, the halfway number is 192 higher than 17 and 192 lower than 401. Therefore, our halfway between answer of 209 above is correct.
