Explanation opens after your attempt
B. (5)
Concept

Why this answer is correct
The correct answer is B. (5). The terms are \(22,17,12,7,2,-3,\ldots\), so there are (5) positive terms. Do not count zero or negative terms as positive.
Exam Tip
पद \(22,17,12,7,2,-3,\ldots\) हैं, इसलिए धनात्मक पद (5) हैं। शून्य और ऋणात्मक पदों को धनात्मक न मानें।
