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 $162$.

$8$	$8$	$12$	$24$
$36$	$(A)$	$(B)$	$(C)$	$(D)$	$(E)$

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