(D) Observe the pattern of differences between consecutive terms:$4 - 2.5 = 1.5$$10 - ? = x$$14.5 - 10 = 4.5$$20 - 14.5 = 5.5$$26.5 - 20 = 6.5$The differences are increasing by $1$ each time: $1.5, 2.5, 3.5, 4.5, 5.5, 6.5$.Therefore,the missing term is $4 + 2.5 = 6.5$.Checking the next step: $6.5 + 3.5 = 10$,which matches the series.

$6$	$10$	$32$	$126$
$2$	$(a)$	$(b)$	$(c)$

Find the missing term in the series: $2.5, 4, ?, 10, 14.5, 20, 26.5$.
