Halfway Between 85 and 661

When you ask "What number is halfway between 85 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=85 and Y=661.

Halfway Between Line

To find the number halfway between 85 and 661, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 85 and 661 into our formula, we get:

(85 + 661)/2 = 373

Thus, the number halfway between 85 and 661 is 373.

To check that our answer is correct, we subtract 85 from 373 and subtract 373 from 661 and compare the two numbers:

373 - 85 = 288
661 - 373 = 288

As you can see, the halfway number is 288 higher than 85 and 288 lower than 661. Therefore, our halfway between answer of 373 above is correct.
