Vedclass · Answer

(B) The given sequence is a combination of two alternating series.First series (odd positions): $1, 3, 9, ?$In this series,each term is multiplied by $3$ to get the next term ($1 	imes 3 = 3$,$3 	imes 3 = 9$,$9 	imes 3 = 27$).Second series (even positions): $2, 6, 18, 54$In this series,each term is also multiplied by $3$ ($2 	imes 3 = 6$,$6 	imes 3 = 18$,$18 	imes 3 = 54$).Therefore,the missing term is $9 	imes 3 = 27$.

$4$	$7$	$24$	$93$
$2$	$(a)$	$(b)$	$(c)$	$(d)$	$(e)$
