Question

Help, medal given!!

Answer 1

im gonna say B?

Answer 2

every time multiply by -4

Answer 3

Well, since the second term is -4 times the first term and the third term is -4 times the second term, I guess I would choose the option that says that.

Answer 4

a1=-2
a2=a1 *q =a1*-4 =-2 *(-4)=8

so a(n)=a1 *q ^(n-1)
a(n)=-2 *(-4)^(n-1)

or a(n)=-4 * a(n-1)
