Halfway Between 7 and 509

When you ask "What number is halfway between 7 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=7 and Y=509.

Halfway Between Line

To find the number halfway between 7 and 509, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 7 and 509 into our formula, we get:

(7 + 509)/2 = 258

Thus, the number halfway between 7 and 509 is 258.

To check that our answer is correct, we subtract 7 from 258 and subtract 258 from 509 and compare the two numbers:

258 - 7 = 251
509 - 258 = 251

As you can see, the halfway number is 251 higher than 7 and 251 lower than 509. Therefore, our halfway between answer of 258 above is correct.
