यदि \(a_1=12\) और (d=-3) है, तो पहले (8) पदों में कितने धनात्मक पद होंगे?
If \(a_1=12\) and (d=-3), how many positive terms are there among the first (8) terms?
Explanation opens after your attempt
B. (4)
Concept
The terms are \(12,9,6,3,0,-3,\ldots\), so there are (4) positive terms. Zero is not counted as positive.
Why this answer is correct
The correct answer is B. (4). The terms are \(12,9,6,3,0,-3,\ldots\), so there are (4) positive terms. Zero is not counted as positive.
Exam Tip
पद \(12,9,6,3,0,-3,\ldots\) हैं, इसलिए धनात्मक पद (4) हैं। शून्य को धनात्मक नहीं मानते।
