(C) The pattern followed in the sequence is $x_{n} = 2 	imes x_{n+1} + 4 	imes k$,where $k$ is a decreasing integer starting from $6$.Step $1$: $864 = 2 	imes 420 + 4 	imes 6 = 840 + 24 = 864$ (Correct)Step $2$: $420 = 2 	imes 200 + 4 	imes 5 = 400 + 20 = 420$ (Correct)Step $3$: $200 = 2 	imes 92 + 4 	imes 4 = 184 + 16 = 200$ (Here,$96$ is incorrect,it should be $92$)Step $4$: $92 = 2 	imes 40 + 4 	imes 3 = 80 + 12 = 92$ (Correct)Step $5$: $40 = 2 	imes 16 + 4 	imes 2 = 32 + 8 = 40$ (Correct)Step $6$: $16 = 2 	imes 6 + 4 	imes 1 = 12 + 4 = 16$ (Correct)Therefore,$96$ is the odd number in the sequence.
