Halfway Between 15 and 343

When you ask "What number is halfway between 15 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=15 and Y=343.

Halfway Between Line

To find the number halfway between 15 and 343, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 15 and 343 into our formula, we get:

(15 + 343)/2 = 179

Thus, the number halfway between 15 and 343 is 179.

To check that our answer is correct, we subtract 15 from 179 and subtract 179 from 343 and compare the two numbers:

179 - 15 = 164
343 - 179 = 164

As you can see, the halfway number is 164 higher than 15 and 164 lower than 343. Therefore, our halfway between answer of 179 above is correct.
