Halfway Between 71 and 309

When you ask "What number is halfway between 71 and 309?" 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=309.

Halfway Between Line

To find the number halfway between 71 and 309, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 71 and 309 into our formula, we get:

(71 + 309)/2 = 190

Thus, the number halfway between 71 and 309 is 190.

To check that our answer is correct, we subtract 71 from 190 and subtract 190 from 309 and compare the two numbers:

190 - 71 = 119
309 - 190 = 119

As you can see, the halfway number is 119 higher than 71 and 119 lower than 309. Therefore, our halfway between answer of 190 above is correct.
