1.) An = (0)n + 2
2.) An = (0)n + 1

Not sure if you still need to put 0 beside n.

I can only answer the numbers 1,2,3,5 only :)

1.)
an=a1+(n-1)d
an=-2+(n-1)4
an=4n-6

2.)
an=a1r^n-1
an=-1^1(-1)^n-1
an=-1^1+n+1
an=-1^n

3.)
 an=a1+(n-1)d
an=3+(n-1) -2
an=3-2n+2
an=-2n+5

5.)
 an=a1+(n-1)d
an=-3+(n-1)5
an=-3+5n-5
an=5n-8

-Hope its helpful :)
