(A) The pattern follows the rule: $(	ext{Previous Term} 	imes n) + (n 	imes (8-n))$,where $n$ is the position index starting from $1$.For $n=1$: $(6 	imes 1) + (1 	imes 7) = 6 + 7 = 13$.For $n=2$: $(13 	imes 2) + (2 	imes 6) = 26 + 12 = 38$.For $n=3$: $(38 	imes 3) + (3 	imes 5) = 114 + 15 = 129$.For $n=4$: $(129 	imes 4) + (4 	imes 4) = 516 + 16 = 532$.For $n=5$: $(532 	imes 5) + (5 	imes 3) = 2660 + 15 = 2675$.Thus,the missing number is $129$.

Find the missing number in the series: $6, 13, 38, ?, 532, 2675$.
