1.	Let V_r denote the sum of the first r terms of an arithmetic progression (AP) whose first term is r and the common difference is (2r-1). Let T_r=V_(r+1)-V_r-2 and Q_r =T_(r+1)-T_r for r=1,2 Which one of the following is a correct statement? (A) Q_1, Q_2, Q_3………….., are in A.P. with common difference 5 (B) Q_1, Q_2, Q_3………….., are in A.P. with common difference 6 (C) Q_1, Q_2, Q_3………….., are in A.P. with common difference 11 (D) Q_1=Q_2=Q_3
Answer» `Q_1,Q_2,Q_3,`.....are in A.P. with COMMON DIFFERENCE 5. `Q_1,Q_2,Q_3,`.....are in A.P. with common difference 6. `Q_1,Q_2,Q_3,`.....are in A.P. with common difference 11. `Q_1=Q_2=Q_3,`...... ANSWER :B
