Answer:

C  a1= -2

    an = an-1 +3

Step-by-step explanation:

an = -2+ (n-1)3

What is the first term?  Let n=1

a1 = -2 + 0*3

a1 = -2


The difference between the  terms is +3  (coefficient on (n-1))

The second term is the first term +3

The third term is the second term plus 3

The next term is the previous term +3

so an = an-1+ 3
