1. nth term=3n-1

20th term=3(20)-1=60-1=59

2. nth term=-2n-4

20th term=-2(20)-4=-40-4=-44

3. nth term= $\frac{2}{3}$ n- $\frac{2}{3}$

20th term= $\frac{2}{3}$ (20)- $\frac{2}{3}$ = $\frac{40}{3}$ - $\frac{2}{3}$ = $\frac{38}{3}$

4. nth term=- $\frac{1}{3}$ n+ $\frac{11}{15}$

20th term=- $\frac{1}{3}$ (20)+ $\frac{11}{15}$ =- $\frac{20}{3}$ + $\frac{11}{15}$ =- $\frac{89}{15}$
