# Recursion Formulas (Sequences)

- 1Given $t_1=3$, Find the first four terms of the sequence determined by:$$ $$ $$t_n=2(t_{n-1})$$
- 2Given $t_1=4$, Find the first four terms of the sequence determined by:$$ $$ $$t_n=-3(t_{n-1})$$
- 3Given $t_1=3$ and $t_2=1$, Find the first five terms of the sequence determined by:$$ $$ $$t_n=t_{n-1}+t_{n-2}$$
- 4Given $t_1=-2$ and $t_2=3$, Find the first five terms of the sequence determined by:$$ $$ $$t_n=2(t_{n-1})-3(t_{n-2})$$
- 5Given $t_1=1$ and $t_2=1$, Find the first five terms of the sequence determined by:$$ $$ $$t_n=(t_{n-1})^2+t_{n-2}$$
- 6Given $t_1=3$. Find the first four terms of the sequence determined by:$$ $$ $$t_n=t_{n-1}+2n$$ $$ $$ Good test question!
- 7Given $t_1=-2$. Find the first four terms of the sequence determined by:$$ $$ $$t_n=n(t_{n-1})$$

$$e=mc^2$$
