Halfway Between 25 and 509

When you ask "What number is halfway between 25 and 509?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=25 and Y=509.

Halfway Between Line

To find the number halfway between 25 and 509, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 25 and 509 into our formula, we get:

(25 + 509)/2 = 267

Thus, the number halfway between 25 and 509 is 267.

To check that our answer is correct, we subtract 25 from 267 and subtract 267 from 509 and compare the two numbers:

267 - 25 = 242
509 - 267 = 242

As you can see, the halfway number is 242 higher than 25 and 242 lower than 509. Therefore, our halfway between answer of 267 above is correct.
