Answer 1

I'll help you to the best I can. :)

Answer 2

Thank you.

Answer 3

So do you understand what a recursive rule is?

Answer 4

No, not really.

Answer 5

A recursive formula always uses the preceding term to define the next term of the sequence. Sequences can have the same formula but because they start with a different number, they are different patterns.

Answer 6

Oh, okay then.

Answer 7

So it's just a sequence of numbers, and you need to find out how they get to one number to the next.

Answer 8

How do I do that then?

Answer 9

Doing the math, hold on. O_o

Answer 10

Take your time.

Answer 11

so to get to each number we multiply by -4, understand?
