Halfway Between 90 and 343

When you ask "What number is halfway between 90 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=90 and Y=343.

Halfway Between Line

To find the number halfway between 90 and 343, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 90 and 343 into our formula, we get:

(90 + 343)/2 = 216.5

Thus, the number halfway between 90 and 343 is 216.5.

To check that our answer is correct, we subtract 90 from 216.5 and subtract 216.5 from 343 and compare the two numbers:

216.5 - 90 = 126.5
343 - 216.5 = 126.5

As you can see, the halfway number is 126.5 higher than 90 and 126.5 lower than 343. Therefore, our halfway between answer of 216.5 above is correct.
