(d)
step-by-step explanation:
given: the line in the graph passes through points (5,30) and (6,26).
then, the equation of line is:
[tex]y-y_{1}=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}(x-x_{1})[/tex]
[tex]y-30=\frac{26-30}{6-5}(x-5)[/tex]
[tex]y-30=-4(x-5)[/tex]
[tex]y-30=-4x+20[/tex]
[tex]y=-4x+50[/tex]
now, put y=a(n) and x=n,
[tex]a(n)=-4n+50[/tex]
[tex]a(n)=-4n+46+4[/tex]
[tex]a(n)=46-(n-1){\times}4[/tex]
hence, option d is correct.
