a. k=3
b. 8
c.-3
a.
\begin{gathered}\frac{2k-1}{k+5} =\frac{4k-2}{2k+1}\\ (2k-1)(2k+1)=(k+5)(4k-2)\\4k^{2} -1=4k^{2} +3k-10\\3k=9\\k=3\end{gathered}
k+5
2k−1
=
2k+1
4k−2
(2k−1)(2k+1)=(k+5)(4k−2)

=8
c.
\begin{gathered}a_{n}=a_{1}+d(n-1)\\a_{12}=8-1(12-1)\\a_{12}=8-1(11)\\a_{12}=8-11\\a_{12}=-3\end{gathered}
