Question

(PLEASE HELP NEED ANSWER ASAP)

Answer 1

C a1= -2

an = an-1 +3

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
