Halfway Between 45 and 661

When you ask "What number is halfway between 45 and 661?" 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=661.

Halfway Between Line

To find the number halfway between 45 and 661, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 45 and 661 into our formula, we get:

(45 + 661)/2 = 353

Thus, the number halfway between 45 and 661 is 353.

To check that our answer is correct, we subtract 45 from 353 and subtract 353 from 661 and compare the two numbers:

353 - 45 = 308
661 - 353 = 308

As you can see, the halfway number is 308 higher than 45 and 308 lower than 661. Therefore, our halfway between answer of 353 above is correct.
