An=N+4, An=2n-1, An=12-3n , An=3n, An=(-2)N

An=n+4

an=2n-1

an=12-3n

an=3n

an=(-2)n

Answer:

an=n+4

a1=1+4 =5

a2=2+4 =6

a3=3+4 =7

an=2n-1

a1=2(1)-1 = 1

a2=2(2)-1 = 3

a3=2(3)-1 = 5

an=12-3n

a1=12-3(1) = 9

a2=12-3(2) = 6

a3=12-3(3) = 3

an=3n

a1=3(1) = 3

a2=3(2) = 6

a3=3(3) = 9

an=(-2)n

a1=(-2)1 =-2

a2=(-2)2 =-4

a3=(-2)3 =-6

and so on...
