OK.

Then learn from me, please, how the question should be.

It should be in this way :

    What is the number of terms in this sequence ?

----------------

Solution

This sequence is the arithmetic progression with the first term    and the common difference  


     ,  ,  ,     and so on  till  2 .


There are 5 terms from    to  1, inclusive.


Then there are 6 terms from  1   to 2, inclusive.


Then there are 5 terms from  2   to  2 , inclusive.


Now, to answer the question, you need to add these quantities: 5, 6 and 5.

Solved.

--------------

As I see from your post, you never opened Math textbook and never read formulations of Math problems from there.

Please MEMORIZE:

    Each Math problem formulation must go with a question,
    similar to as you see in my post.


    It is a neutral and polite form formulating Math problem.


    It is NOT a polite way to complete your post with the words "I need to know . . . "
