Let `S_n(n leq 1)` be a sequence of sets defined by `S_1{0},S_2={3/2,5/2},S_3={15/4,19/4,23/4,27/4},.......`then

Let S_n(n ge 1) be a sequence of sets defined by S_1={0},S_2={3/2,5/2},S_4={15/4,19/4,23/4,27/4},....... then

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, 10/3} , S_(4) = {5/4, 9/4, 13/4, 17/4} ,........ . Then the sum of the set S_(25) is
