] | Your homogeneous solution has $2^n$ in it already. When this happens, for the particular solution part, we cannot just use $C2^n$ (you have seen what happens if we do). Instead, *the rule in this scenario is to modify the guess by **multiplying by $\boldsymbol{n}$**, i.e. try $a\_n^{(p)}=C\color{red}{n}\cdot 2^n$*. | Here is another take.
Let $b\_n=2^n$. Then
$$
a\_n=2a\_{n-1}+2b\_{n-1}, \quad b\_n=2b\_{n-1}, \quad b\_0=1
$$
and so
$$
\pmatrix{
a\_n \\ b\_n
}
=
\pmatrix{
2 & 2 \\ 0 & 2
}
\pmatrix{
a\_{n-1} \\ b\_{n-1}
}
=
2
\pmatrix{
1 & 1 \\ 0 & 1
}
\pmatrix{
a\_{n-1} \\ b\_{n-1}
}$$
which gives
$$
\pmatrix{
a\_n \\ b\_n
}
=
2^n

``` | You can do it in an [ingest pipeline](https://gist.github.com/cdahlqvist/e713b39f0c17d85e613f56408a7facd5). That means the script is executed in elasticsearch, so it has the advantage of including any delays caused by back-pressure from the output. |
