Halfway Between 45 and 647

When you ask "What number is halfway between 45 and 647?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=45 and Y=647.

Halfway Between Line

To find the number halfway between 45 and 647, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 45 and 647 into our formula, we get:

(45 + 647)/2 = 346

Thus, the number halfway between 45 and 647 is 346.

To check that our answer is correct, we subtract 45 from 346 and subtract 346 from 647 and compare the two numbers:

346 - 45 = 301
647 - 346 = 301

As you can see, the halfway number is 301 higher than 45 and 301 lower than 647. Therefore, our halfway between answer of 346 above is correct.
