Halfway Between 90 and 347

When you ask "What number is halfway between 90 and 347?" 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=347.

Halfway Between Line

To find the number halfway between 90 and 347, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 90 and 347 into our formula, we get:

(90 + 347)/2 = 218.5

Thus, the number halfway between 90 and 347 is 218.5.

To check that our answer is correct, we subtract 90 from 218.5 and subtract 218.5 from 347 and compare the two numbers:

218.5 - 90 = 128.5
347 - 218.5 = 128.5

As you can see, the halfway number is 128.5 higher than 90 and 128.5 lower than 347. Therefore, our halfway between answer of 218.5 above is correct.
