$p_n=p_{n-1}+4$
$\implies p_{17}=p_{16}+4$
$\implies p_{17}=p_{15}+2\cdot4$
$\implies p_{17}=p_{14}+3\cdot4$
$\implies p_{17}=\cdots=p_3+14\cdot4$

$\implies74=p_3+56\implies p_3=18$

Mathematics

First find the slope
Y-y

X-x

2/3 is the slope
Next find the slope of the other line
-2y -3x=13
-2y=3x+ 13
Y=-2/3+-6.5
No the lines are perpendicular not parallel
