Halfway Between 17 and 797

When you ask "What number is halfway between 17 and 797?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=17 and Y=797.

Halfway Between Line

To find the number halfway between 17 and 797, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 17 and 797 into our formula, we get:

(17 + 797)/2 = 407

Thus, the number halfway between 17 and 797 is 407.

To check that our answer is correct, we subtract 17 from 407 and subtract 407 from 797 and compare the two numbers:

407 - 17 = 390
797 - 407 = 390

As you can see, the halfway number is 390 higher than 17 and 390 lower than 797. Therefore, our halfway between answer of 407 above is correct.
