Halfway Between 5 and 421

When you ask "What number is halfway between 5 and 421?" 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=421.

Halfway Between Line

To find the number halfway between 5 and 421, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 5 and 421 into our formula, we get:

(5 + 421)/2 = 213

Thus, the number halfway between 5 and 421 is 213.

To check that our answer is correct, we subtract 5 from 213 and subtract 213 from 421 and compare the two numbers:

213 - 5 = 208
421 - 213 = 208

As you can see, the halfway number is 208 higher than 5 and 208 lower than 421. Therefore, our halfway between answer of 213 above is correct.
