Asked by KAYLA
I am doing a practice test and I am stuck on a couple of questions.
1.) Write a rule for the following sequence
8, -1, -10, -19
2.) Find the next three terms of the sequence
-2, -12, -72, -432
3.) Which explains why the sequence 81, 3, 1/9
thanks

1.) 9 is subtracted from the previous number.
What rules do you see for the others?

1. arithmetic sequence with a = 8 and d = -9
2. geometric series with first term -2 and ratio r = 6
3. geometric again r = (1/9)
