When you ask "What number is halfway between 1 and 101?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=1 and Y=101.

To find the number halfway between 1 and 101, we use the following formula:
(X + Y)/2 = Halfway Between
When we enter 1 and 101 into our formula, we get:
(1 + 101)/2 = 51
Thus, the number halfway between 1 and 101 is 51.
To check that our answer is correct, we subtract 1 from 51 and subtract 51 from 101 and compare the two numbers:
51 - 1 = 50
101 - 51 = 50
As you can see, the halfway number is 50 higher than 1 and 50 lower than 101. Therefore, our halfway between answer of 51 above is correct.
