Answer 1

Bom Dia!

$\begin{bmatrix}a11\\a21\\a31\\a41\\a51\\\end{bmatrix}$

$\mathit{a11}\Rightarrow\mathit{1-1}\times\textup{2}\Rightarrow\mathit{1-2}=\boxed{-1}$

$\mathit{a21}\Rightarrow\mathit{2-1}\times\textup{2}\Rightarrow\mathit{2-2}=\boxed{0}$

$\mathit{a31}\Rightarrow\mathit{3-1}\times\textup{2}\Rightarrow\mathit{3-2}=\boxed{1}$

$\mathit{a41}\Rightarrow\mathit{4-1}\times\textup{2}\Rightarrow\mathit{4-2}=\boxed{2}$

$\mathit{a51}\Rightarrow\mathit{5-1}\times\textup{2}\Rightarrow\mathit{5-2}=\boxed{3}$

$\begin{bmatrix}a11\\a21\\a31\\a41\\a51\\\end{bmatrix}$=$\begin{bmatrix}-1\\0\\1\\2\\3\\\end{bmatrix}$
