righjt the rule of the sequence 3,-3,-9,-15
A Start with 3 and add -6 repeatedly
B start with -6 and add 3 repeatedly
C start with 3 and add 6 repeatedly
D start with 3 and add -6 repeatedly
D start with 3 and add -6 repeatedly
To determine the rule of the sequence 3, -3, -9, -15, we can examine the differences between consecutive terms.
3 - (-3) = 6
-3 - (-9) = 6
-9 - (-15) = 6
We can observe that the differences between consecutive terms are the same (6), indicating a regular pattern.
To find the rule of the sequence, we can choose one of the given options and test if it fits the pattern.
A: Start with 3 and add -6 repeatedly:
3 + (-6) = -3
-3 + (-6) = -9
-9 + (-6) = -15
Applying option A, we can see that this rule fits the sequence, as it gives us the correct terms.
Therefore, the answer is: A) Start with 3 and add -6 repeatedly.
