Halfway Between 51 and 409

When you ask "What number is halfway between 51 and 409?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=51 and Y=409.

Halfway Between Line

To find the number halfway between 51 and 409, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 51 and 409 into our formula, we get:

(51 + 409)/2 = 230

Thus, the number halfway between 51 and 409 is 230.

To check that our answer is correct, we subtract 51 from 230 and subtract 230 from 409 and compare the two numbers:

230 - 51 = 179
409 - 230 = 179

As you can see, the halfway number is 179 higher than 51 and 179 lower than 409. Therefore, our halfway between answer of 230 above is correct.
