Halfway Between 55 and 661

When you ask "What number is halfway between 55 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=55 and Y=661.

Halfway Between Line

To find the number halfway between 55 and 661, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 55 and 661 into our formula, we get:

(55 + 661)/2 = 358

Thus, the number halfway between 55 and 661 is 358.

To check that our answer is correct, we subtract 55 from 358 and subtract 358 from 661 and compare the two numbers:

358 - 55 = 303
661 - 358 = 303

As you can see, the halfway number is 303 higher than 55 and 303 lower than 661. Therefore, our halfway between answer of 358 above is correct.
