Halfway Between 67 and 509

When you ask "What number is halfway between 67 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=67 and Y=509.

Halfway Between Line

To find the number halfway between 67 and 509, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 67 and 509 into our formula, we get:

(67 + 509)/2 = 288

Thus, the number halfway between 67 and 509 is 288.

To check that our answer is correct, we subtract 67 from 288 and subtract 288 from 509 and compare the two numbers:

288 - 67 = 221
509 - 288 = 221

As you can see, the halfway number is 221 higher than 67 and 221 lower than 509. Therefore, our halfway between answer of 288 above is correct.
