Halfway Between 1 and 421

When you ask "What number is halfway between 1 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=1 and Y=421.

Halfway Between Line

To find the number halfway between 1 and 421, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 1 and 421 into our formula, we get:

(1 + 421)/2 = 211

Thus, the number halfway between 1 and 421 is 211.

To check that our answer is correct, we subtract 1 from 211 and subtract 211 from 421 and compare the two numbers:

211 - 1 = 210
421 - 211 = 210

As you can see, the halfway number is 210 higher than 1 and 210 lower than 421. Therefore, our halfway between answer of 211 above is correct.
