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  2%2F6  and the common difference  1%2F6


    2%2F6 ,  3%2F6,  4%2F6,  5%2F6   and so on  till  2 5%2F6.


There are 5 terms from  2%2F6  to  1, inclusive.


Then there are 6 terms from  1 1%2F6  to 2, inclusive.


Then there are 5 terms from  2 1%2F6  to  2 5%2F6, 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 . . . "
