Vedclass · Answer

(B) Observe the pattern of the series by calculating the ratio between consecutive terms:$72 / 108 = 2/3$$48 / 72 = 2/3$This is a geometric progression where each term is multiplied by $2/3$ to get the next term.Let the missing term be $x$.Then,$x = 243 	imes (2/3) = 81 	imes 2 = 162$.To verify,$162 	imes (2/3) = 54 	imes 2 = 108$.The pattern holds true. Thus,the missing number is $162$.

$6$	$3.0$	$4.5$	$2.25$
$40$	$(a)$	$(b)$	$(c)$	$(d)$	$(e)$

$2$	$17$	$121$	$729$
$5$	$(a)$	$(b)$	$(c)$

$1$	$9$	$65$	$393$
$2$	$(a)$	$(b)$	$(c)$

Find the missing number in the series: $243, \dots, 108, 72, 48$.
