Question

Write the recursive formula for the geometric sequence.

a1 = -2 a2 = 8 a3 = -32

Answer 1

look the difference between -2 and 8
\[−2^{1}=−2\]

\[−2^{1+n}=8\]

Answer 2

i guess you can figure out

Answer 3

noo

Answer 4

an = -4 • an-1 ?

Answer 5

\[-2^{1+(2 \times 0)}=-2, -2^{1+(2 \times 1)}=8, -2^{1+(2 \times 2)}=-32\]
