Answer:

$a_{6} = 1215 \\ a_{8} = - 49152 \\ a_{5} = \frac{3}{64}$

Step-by-step explanation:

Using the Geometric Sequence Formula

$a_{n} = a_{1}{r}^{n - 1}$

1. a1 = 5, r = 3, n = 6, a6 = ?

$a_{6} = (5){(3)}^{6 - 1} \\ a_{6} = (5)(243) \\ a_{6} = 1215$

2. a1 = 3, r = -4, n = 8, a8 = ?

$a_{8} = (3){( - 4)}^{8 - 1} \\ a_{8} = (3)( - 16384) \\ a_{8} = - 49152$

3. a1 = 3/4, r = 1/2, n = 5, a5 = ?

$a_{5} = ( \frac{3}{4}){( \frac{1}{2})}^{5 - 1} \\ a_{5} = ( \frac{3}{4} )( \frac{1}{16} ) \\ a_{5} = \frac{3}{64}$

Hope this helps
