(2(3m+1)=(2m-3)+(5m-2)) से (6m+2=7m-5), इसलिए (m=7) और (d=22-11=11)। पहले चर निकालें, फिर क्रमागत अंतर निकालें। / From (2(3m+1)=(2m-3)+(5m-2)), (6m+2=7m-5), so (m=7) and (d=22-11=11). Find the variable first, then the consecutive difference.
Mathematics Answer, Explanation and Revision Hints
यदि (2m-3, 3m+1, 5m-2) अंकगणितीय श्रेणी में हैं, तो सार्व अंतर क्या होगा? / If (2m-3, 3m+1, 5m-2) are in an arithmetic progression, what will be the common difference?
Correct Answer: B. (7). Explanation: (2(3m+1)=(2m-3)+(5m-2)) से (6m+2=7m-5), इसलिए (m=7) और (d=22-11=11)। पहले चर निकालें, फिर क्रमागत अंतर निकालें। / From (2(3m+1)=(2m-3)+(5m-2)), (6m+2=7m-5), so (m=7) and (d=22-11=11). Find the variable first, then the consecutive difference.
