If `S_1=Sigman, S_2=Sigman^2,S_3=Sigma n^3, "then the value of " lim_(n to oo) (S_1(1+(S_3)/(8)))/(S_2^2)` is equal to

If S_(1) = sumn, S_(2) = sumn^(2), S_(3) = sumn^(3) then lim_(n rarr oo) (s_(1)(1+s_(3)/8))/(s_(2)^(2)) =

If Sigman, ( sqrt(10))/( 3)Sigman^(2) , Sigman^(3) are in G.P., then the value of n is :
