Vedclass · Answer

(A) The given series is $60, 20, ?, 15, 60, 12$.Let's analyze the pattern between consecutive terms:$60 	imes \frac{1}{3} = 20$$20 	imes 3 = 60$$60 	imes \frac{1}{4} = 15$$15 	imes 4 = 60$$60 	imes \frac{1}{5} = 12$The pattern follows alternating operations: multiply by $\frac{1}{n}$ and then multiply by $n$,where $n$ increases by $1$ in each step $(n = 3, 4, 5, \dots)$.Therefore,the missing term is $20 	imes 3 = 60$.

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

Find the missing number in the series: $60, 20, ?, 15, 60, 12$.
