Vedclass · Answer

(D) Observe the pattern between consecutive terms:$2 	imes 3 + 12 = 18$$18 	imes 3 + 12 = 66$$66 	imes 3 + 12 = 210$$210 	imes 3 + 12 = 642$Alternatively,each term $T_n$ follows the rule $T_{n+1} = (T_n + 4) 	imes 3$.Applying this to the last term:$(642 + 4) 	imes 3 = 646 	imes 3 = 1938$.
