Halfway Between 77 and 210

When you ask "What number is halfway between 77 and 210?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=77 and Y=210.

Halfway Between Line

To find the number halfway between 77 and 210, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 77 and 210 into our formula, we get:

(77 + 210)/2 = 143.5

Thus, the number halfway between 77 and 210 is 143.5.

To check that our answer is correct, we subtract 77 from 143.5 and subtract 143.5 from 210 and compare the two numbers:

143.5 - 77 = 66.5
210 - 143.5 = 66.5

As you can see, the halfway number is 66.5 higher than 77 and 66.5 lower than 210. Therefore, our halfway between answer of 143.5 above is correct.
