Halfway Between 85 and 343

When you ask "What number is halfway between 85 and 343?" 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=343.

Halfway Between Line

To find the number halfway between 85 and 343, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 85 and 343 into our formula, we get:

(85 + 343)/2 = 214

Thus, the number halfway between 85 and 343 is 214.

To check that our answer is correct, we subtract 85 from 214 and subtract 214 from 343 and compare the two numbers:

214 - 85 = 129
343 - 214 = 129

As you can see, the halfway number is 129 higher than 85 and 129 lower than 343. Therefore, our halfway between answer of 214 above is correct.
