Find the general term for the following sequences.

(i)

$3$ ,

$6$ ,

$9$ , …

$a_n = 4n$
$a_n = 6n$
$a_n = 2n$
$a_n = 3n$

(ii)

$\frac{1}{2}, \frac{2}{3}, \frac{3}{4}, ...$

$a_{n} = n - \frac{1}{n}$
$a_{n} = \frac{n}{n + 1}$
$a_{n} = n + \frac{1}{n}$
$a_{n} = \frac{n + 1}{n}$

(iii)

$5$ ,

$-25$ ,

$125$ , …

$a_n = (-1)^{n + 1} 5^n$
$a_n = (-1)^{n} 5^n$
$a_n = (-1)^{n + 1} 5n$
$a_n = (-1)^{n} 5^{n + 1}$
