How many numbers are in between 1 and 2?

There are infinitely many numbers between 1 and 2. This includes not just the whole numbers, but also fractions, decimals, and Irrational Numbers. For example, numbers like 1.1, 1.5, 1.75, and even 1.414 are all between 1 and 2. Thus, no finite count can capture all the numbers in that interval.
