$4$	$9$	$25$	$103$
$3$	$(a)$	$(b)$	$(c)$

Which of the following numbers will come in place of $(c)$?

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 sequence of the original series and answer the questions that follow the series.

$85$	$43$	$44$	$67.5$	$137$	$345$
$125$	$(a)$	$(b)$	$(c)$	$(d)$	$(e)$

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

Find the next term in the series: $3, 15, 39, 75, 123, 183, ?$

Observe the following table and determine the value that should replace $(e)$:

$12$	$28$	$64$	$140$
$37$	$(a)$	$(b)$	$(c)$	$(d)$	$(e)$

$7, 11, 23, 51, 103, (?)$

Find the missing term in the series: $39, 52, 78, 117, 169, ?$
