Halfway Between 71 and 215

When you ask "What number is halfway between 71 and 215?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=71 and Y=215.

Halfway Between Line

To find the number halfway between 71 and 215, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 71 and 215 into our formula, we get:

(71 + 215)/2 = 143

Thus, the number halfway between 71 and 215 is 143.

To check that our answer is correct, we subtract 71 from 143 and subtract 143 from 215 and compare the two numbers:

143 - 71 = 72
215 - 143 = 72

As you can see, the halfway number is 72 higher than 71 and 72 lower than 215. Therefore, our halfway between answer of 143 above is correct.
