If (2n) is added to each term of (12, 9, 6, 3,\ldots), where (n) is the term number, what will be the new common difference?यदि (12, 9, 6, 3,\ldots) के प्रत्येक पद में (2n) जोड़ा जाए, जहां (n) पद संख्या है, तो नया सार्व अंतर क्या होगा?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (-1)(-1)
The original (d=-3), and the difference of (2n) is (2), so the new (d=-3+2=-1). For term-number changes, add or subtract its difference.मूल (d=-3) है और (2n) का अंतर (2) है, इसलिए नया (d=-3+2=-1)। पद संख्या वाले परिवर्तन में उसके अंतर को जोड़ें या घटाएं।
