Halfway Between 51 and 225

When you ask "What number is halfway between 51 and 225?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=51 and Y=225.

Halfway Between Line

To find the number halfway between 51 and 225, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 51 and 225 into our formula, we get:

(51 + 225)/2 = 138

Thus, the number halfway between 51 and 225 is 138.

To check that our answer is correct, we subtract 51 from 138 and subtract 138 from 225 and compare the two numbers:

138 - 51 = 87
225 - 138 = 87

As you can see, the halfway number is 87 higher than 51 and 87 lower than 225. Therefore, our halfway between answer of 138 above is correct.
