The sets `S_1,S_2,S_3,` .......... are given by `S_1={2/1},S_2={3/2,5/2},S_3={4/3,7/3(10)/3},S_4={5/4,9/4,(13)/4,(17)/4}, ddot` Then the sum of the numbers in the set `S_(25)` is 320 (b) 322 (c) 326 (d) 325

The sets S_(1),S_(2),S_(3),............ are given by S_(1)={(2)/(1)},S_(2)={(3)/(2),(5)/(2)},S_(3)={(4)/(3),(7)/(3)},S_(4)={(5)/(4),(9)/(4),(13)/(4),(17)/(4)},.... Then the sum of the numbers in the set S_(25) is 320(b)322(c)326 (d) 325

The sets S_(1), S_(2), S_(3), …………. are given by S_(1) = {2/1} , S_(2) = {3/2, 5/2} , S_(3) = {4/3, 7/3, 10/3} , S_(4) = {5/4, 9/4, 13/4, 17/4} ,........ . Then the sum of the set S_(25) is

The sets S_(1),S_(2),S_(3),… are given by S_(1)={(2)/(1)} , S_(2)={(3)/(2),(5)/(2)} , S_(3)={(4)/(3),(7)/(3),(10)/(3)} , S_(4)={(5)/(4),(9)/(4),(13)/(4),(17)/(4)},... Then, the sum of the numbers in the set S_(25) is

If S_(1) = {2}, S_(2) = {3,6}, S_(3) = {4,8,16}, S_(4) = { 5,10, 20, 40}, …...... then the sum of numbers in the set S_(15) is

If S_(1)={2},S_(2)={3,6},S_(3)={4,8,16},S_(4)={5,10,20,40} then the sum of numbers in the set S_(15) is

S_(1)={2},S_(2)={(3)/(2),(4)/(2)},S_(3)={(4)/(4),(5)/(4),(6)/(4)},S_(4)={(5)/(8),(6)/(8),(7)/(8),(8)/(8)}, then the sum of numbers in S_(20) is

The sets S_(1) , S_(2) , S_(3) , …. are given by S_(1) = {(2)/(1) } , S_(2) = { (3)/(2) , (5)/(2) } , S_(3) = { (4)/(3) , (7)/( 3) , (10)/( 3) } , S_(4) = { ( 5)/( 4) , (9)/( 4) , (13)/( 4) , (17)/( 4) }, ….. then the sum of the numbers in the set S_25) is
