When you ask "What number is halfway between 51 and 195?" 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=195.
To find the number halfway between 51 and 195, we use the following formula:
(X + Y)/2 = Halfway Between
When we enter 51 and 195 into our formula, we get:
(51 + 195)/2 = 123
Thus, the number halfway between 51 and 195 is 123.
To check that our answer is correct, we subtract 51 from 123 and subtract 123 from 195 and compare the two numbers:
123 - 51 = 72
195 - 123 = 72
As you can see, the halfway number is 72 higher than 51 and 72 lower than 195. Therefore, our halfway between answer of 123 above is correct.
