Answer:
3, -6, 12, -24, 48
Step-by-step explanation:
Given:
- [tex]a_1=3[/tex]
- [tex]a_{n+1}=-2 \cdot a_n[/tex]
Therefore,
[tex]a_1=3[/tex]
[tex]a_2=-2 \cdot a_1=-2 \cdot 3=-6[/tex]
[tex]a_3=-2 \cdot a_2=-2 \cdot -6=12[/tex]
[tex]a_4=-2 \cdot a_3=-2 \cdot 12=-24[/tex]
[tex]a_5=-2 \cdot a_4=-2 \cdot -24=48[/tex]
