the lang of ur ques is a bit unclear. however i ll try my best to ans it.let the no. of inital diamonds be A_0.after thief 1 commits his crime, let the no of diamonds LEFT be A_1.similarly after thief 2 commits his crime, let the no of diamonds LEFT be A_2 and so on.....clearly, A_(n+1) = A_n – (A_n/2 + 1)or 2[1 + A_(n+1)] = A_nalso, A_4= 0So, A_3= 2(1+0)= 2so A_2= 2(1+2)= 6so A_1= 2(1+6)= 14or A_0= 2(1+14)= 30Hence there were 30 diamonds initially.KINDLY APPROVE :))
