$56, 63, 70, 77, ?$

In each of the following questions a number series is given. After the series a number is given followed by $(a), (b), (c), (d)$ and $(e).$ You have to complete the series starting with the number given,following the same pattern as the original series.

$12$	$30$	$120$	$460$	$1368$	$2730$
$16$	$(a)$	$(b)$	$(c)$	$(d)$	$(e)$

What will come in place of $(d)?$

If $A = \left(\frac{1}{0.4}\right) + \left(\frac{1}{0.04}\right) + \left(\frac{1}{0.004}\right) + \dots$ up to $8$ terms,then what is the value of $A$ (in $.5$)?

Find out the odd number from the given sequence: $37, 47, 52, 67, 87, 112, 142$.
