Answer:

A.

1. r = 4

2. r = 1/2

3. r = -3

4. r = 2

B.

1. g7 = 1,458

2.

[tex]g_{1} =512 \\r= \frac{1}{4} \\g_{5} = 2\\\\g_{n} = g_{1} r^{n-1} \\g_{5} = 512(\frac{1}{4} )^{5-1} \\\\\\g_{5} = 512(\frac{1}{4} )^{(4)\\\\g_{5} = 512(\frac{1}{256} )\\g_{5} = 2[/tex]

3.

[tex]g_{2} = 5\\g_{4} = 125\\\\g_{1} = 1\\r = 5\\g_{5} =625\\\\g_{5} =g_{1} r^{n-1} \\g_{5} =1 (5)^{5-1} \\g_{5} =1 (5)^{4} \\g_{5} =625[/tex]
