(D) The pattern of the sequence is $x_{n} = x_{n-1} 	imes (n-1) + (n-1)$,where $n$ is the position of the term.For $n=2$: $1 	imes 1 + 1 = 2$For $n=3$: $2 	imes 2 + 2 = 6$For $n=4$: $6 	imes 3 + 3 = 21$For $n=5$: $21 	imes 4 + 4 = 88$ (but the given term is $84$)For $n=6$: $88 	imes 5 + 5 = 445$For $n=7$: $445 	imes 6 + 6 = 2676$Since $88$ is the correct term for the $5^{th}$ position,$84$ is the odd number in the sequence.
