Dear student,
The above concept can be fully cleared out by the concept of AP(arithmetic progression) which you will learn in class 9/10.
For the time being, I suggest you to remember this concept.
For now, I am trying to make you understand through e.g,
For eg.,
Count number between 2 to 10
As, between is given thus 2 and 10 will not be counted.
Nos. are: 2,3,4,5,6,7,8,9,10
We will only count bold ones i.e, 7
Now using the formula you provided: 10-2-1=7
Regards
