What is the explicit rule for the sequence?

 

 

\(\begin{array}{|rcll|} \hline 34 \\ & -8 \\ 26 \\ & -8 \\ 18 \\ & -8 \\ 10 \\ \hline \end{array}\)

 

\(\text{arithmetical sequence: $\\$ $a_n = a_1 + (n-1)d \\$ } \\ \text{ $a_1 =34 $ and $d=-8 $ } \)

 

\(\begin{array}{|rcll|} \hline a_n &=& a_1 + (n-1)d \\ a_n &=& 34 + (n-1)(-8) \\ a_n &=& 34-8n+8 \\ \mathbf{a_n} & \mathbf{=} & \mathbf{42-8n} \\ \hline \end{array}\)
