$f \left(2\right) = 3$

Explanation:

[1]$\textcolor{w h i t e}{\text{XXX}} f$ is a function which defines the sequence
[2]$\textcolor{w h i t e}{\text{XXX}}$the first element of the given sequence is $f \left(1\right)$
$\textcolor{w h i t e}{\text{XXX}} f \left(1\right) = - 7$
$\textcolor{w h i t e}{\text{XXX}} f \left(2\right) = 3$
$\textcolor{w h i t e}{\text{XXX}} f \left(3\right) = 1$
$\textcolor{w h i t e}{\text{XXX}} f \left(4\right) = 5$
$\textcolor{w h i t e}{\text{XXX}} f \left(5\right) = 9$
