Halfway Between 15 and 693

When you ask "What number is halfway between 15 and 693?" 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=693.

Halfway Between Line

To find the number halfway between 15 and 693, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 15 and 693 into our formula, we get:

(15 + 693)/2 = 354

Thus, the number halfway between 15 and 693 is 354.

To check that our answer is correct, we subtract 15 from 354 and subtract 354 from 693 and compare the two numbers:

354 - 15 = 339
693 - 354 = 339

As you can see, the halfway number is 339 higher than 15 and 339 lower than 693. Therefore, our halfway between answer of 354 above is correct.
