यदि \(1, 4, 7, 10,\ldots\) के प्रत्येक पद में उसकी पद संख्या जोड़ दी जाए, तो नया (d) क्या होगा?
If each term of \(1, 4, 7, 10,\ldots\) is increased by its term number, what will be the new (d)?
Explanation opens after your attempt
B. (4)
Concept
The original (d=3), and term numbers \(1,2,3,\ldots\) have difference (1), so the new (d=4). In this transformation, add the two common differences.
Why this answer is correct
The correct answer is B. (4). The original (d=3), and term numbers \(1,2,3,\ldots\) have difference (1), so the new (d=4). In this transformation, add the two common differences.
Exam Tip
मूल (d=3) है और पद संख्या \(1,2,3,\ldots\) का अंतर (1) है, इसलिए नया (d=4)। ऐसे परिवर्तन में दोनों सार्व अंतरों को जोड़ें।
