Halfway Between 10 and 428

When you ask "What number is halfway between 10 and 428?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=10 and Y=428.

Halfway Between Line

To find the number halfway between 10 and 428, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 10 and 428 into our formula, we get:

(10 + 428)/2 = 219

Thus, the number halfway between 10 and 428 is 219.

To check that our answer is correct, we subtract 10 from 219 and subtract 219 from 428 and compare the two numbers:

219 - 10 = 209
428 - 219 = 209

As you can see, the halfway number is 209 higher than 10 and 209 lower than 428. Therefore, our halfway between answer of 219 above is correct.
