If (2, 7, 12,\ldots) is subtracted term by term from (30, 24, 18,\ldots), what will be the common difference of the new sequence?यदि (30, 24, 18,\ldots) से (2, 7, 12,\ldots) को पद-दर-पद घटाया जाए, तो नए अनुक्रम का सार्व अंतर क्या होगा?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (-11)(-11)
The first sequence has (d=-6) and the second has (d=5), so the difference sequence has (d=-6-5=-11). In termwise subtraction, the common differences also subtract.पहले अनुक्रम का (d=-6) और दूसरे का (d=5) है, इसलिए अंतर अनुक्रम का (d=-6-5=-11)। पद-दर-पद घटाव में (d) भी घटते हैं।
