Halfway Between 51 and 321

When you ask "What number is halfway between 51 and 321?" 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=321.

Halfway Between Line

To find the number halfway between 51 and 321, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 51 and 321 into our formula, we get:

(51 + 321)/2 = 186

Thus, the number halfway between 51 and 321 is 186.

To check that our answer is correct, we subtract 51 from 186 and subtract 186 from 321 and compare the two numbers:

186 - 51 = 135
321 - 186 = 135

As you can see, the halfway number is 135 higher than 51 and 135 lower than 321. Therefore, our halfway between answer of 186 above is correct.
