Halfway Between 15 and 425

When you ask "What number is halfway between 15 and 425?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=15 and Y=425.

Halfway Between Line

To find the number halfway between 15 and 425, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 15 and 425 into our formula, we get:

(15 + 425)/2 = 220

Thus, the number halfway between 15 and 425 is 220.

To check that our answer is correct, we subtract 15 from 220 and subtract 220 from 425 and compare the two numbers:

220 - 15 = 205
425 - 220 = 205

As you can see, the halfway number is 205 higher than 15 and 205 lower than 425. Therefore, our halfway between answer of 220 above is correct.
