Question

Havent done this in a while..
Write a formula for the general term (the nth term) of the geometric sequence.

Answer 1

\[\frac{ 1 }{ 2 }, \frac{ 1 }{ -10 }, \frac{ 1 }{ 50 }, \frac{ 1 }{ -250 }\]

Answer 2

i so totally forgot how to do this !

Answer 3

bear with me... its been a while for me to
geom seq
\[a _{n} = a \times r ^{n-1}\]??? i think?

Answer 4

i dont even know lol .

Answer 5

a = ur initial
r = ur ratio or constant or whatever u call it
n = the term in the sequence you want

Answer 6

n would be -5 ?

Answer 7

1 over -5...?
term 2 divided by term 1

Answer 8

so 1/-10 divided by 1/2 = 1/-5

Answer 9

or r would be -5

Answer 10

okay

Answer 11

r = 1/-5...
n = whichever term we want

Answer 12

a = 1/2
... im pretty sure that's all we need for the equation hey ;D

Answer 13

hold on im going to post the answers

Answer 14

\[A. a \eta = (\frac{ 1 }{ 2 }) n-1 \frac{ 3 }{ 5 }\]

Answer 15

B.
