College Algebra, Chapter 9, 9.1, Section 9.1, Problem 12

Determine the first four terms and the 100th term of the sequence $ a_n = 3$
We have $n = 1,2,3,4$ for the first four terms $n = 100$th for 100th term

$
\left.
\begin{equation}
\begin{aligned}
a_1 &= 3 \\
\\
a_2 &= 3\\
\\
a_3 &= 3 \\
\\
a_4 &= 3
\end{aligned}
\end{equation}
\right\} \text{ First four terms}
$

$a_{100} = 3 \rightarrow \text{100th term}$
