# Recursion Formulas (Sequences)

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

$$e=mc^2$$
