The problem statement is not complete. Are they asking you to find the nth term of the arithmetic progression, or its sum to n terms? Or something else?

If it's asking to find the number of terms, then it could possibly mean to find the number of terms that are positive? Because clearly this sequence can go on forever.

the question demands the no. of terms only..it seems impossible to solve...:/

Did you copy this question verbatim from what a teacher said/wrote on the board or do you actually have the physical question in front of you?

Well you could have found the general term :

T_n = a+(n-1)d

but n is not given !

Now your limit isn't specified ! This arithmetic progression can go on forever. However we know that its sum will be less than 0.

But its unending ! So if seriously this is your question then answer will be that number of terms are infinite.

I'm guessing that the book is not written in English. Is it possible that something got lost in the translation?

 

[lionel messi.]

it might be but during printing not translation.the book is in english...!

What is the title of the book, then? Where is the problem in the book?
