Answer
a) $12,6,4,3,2.4,2,\dfrac{12}{7},1.5,\dfrac{4}{3},1.2$
b) See graph
Work Step by Step
a) We calculate the first ten terms of the sequence $a_n=\dfrac{12}{n}$:
$$\begin{align*}
a_1&=\dfrac{12}{1}=12\\
a_2&=\dfrac{12}{2}=6\\
a_3&=\dfrac{12}{3}=4\\
a_4&=\dfrac{12}{4}=3\\
a_5&=\dfrac{12}{5}=2.4\\
a_6&=\dfrac{12}{6}=2\\
a_7&=\dfrac{12}{7}\\
a_8&=\dfrac{12}{8}=1.5\\
a_9&=\dfrac{12}{9}=\dfrac{4}{3}\\
a_{10}&=\dfrac{12}{10}=1.2.
\end{align*}$$
b) Graph the first ten terms:
