Halfway Between 55 and 290

When you ask "What number is halfway between 55 and 290?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=55 and Y=290.

Halfway Between Line

To find the number halfway between 55 and 290, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 55 and 290 into our formula, we get:

(55 + 290)/2 = 172.5

Thus, the number halfway between 55 and 290 is 172.5.

To check that our answer is correct, we subtract 55 from 172.5 and subtract 172.5 from 290 and compare the two numbers:

172.5 - 55 = 117.5
290 - 172.5 = 117.5

As you can see, the halfway number is 117.5 higher than 55 and 117.5 lower than 290. Therefore, our halfway between answer of 172.5 above is correct.
