write a rule for the sequence 3, -3, -9, -15
A. starts with 3 and add -6 repeatedly***
B. starts with -6 and add 3 repeatedly
C. starts with 3 and add 6 repeatedly
D. starts with 3 and subtract -6 repeatedly
looks good to me
A - yes
Thank you both!
To determine the rule for the given sequence 3, -3, -9, -15, we need to identify the pattern and the operation used to generate each term.
In this sequence, each term is generated by subtracting 6 from the previous term. We can verify this by observing the differences between the terms:
-3 - 3 = -6
-9 - (-3) = -6
-15 - (-9) = -6
So, the correct answer is option A: starts with 3 and add -6 repeatedly.
