write a rule for the sequnce.
3,-3,-9,-15
a.start with 3 and add -6 repeatedly
b.start with -6 snd add 3 repeatedly
c.start with 3 and add 6 repeatedly
d.start with 3 an subtract -6 repeatedly
To write a rule for the given sequence 3, -3, -9, -15, we need to observe the pattern and identify how each term relates to the previous one.
Looking at the sequence, we can see that each number is obtained by subtracting 6 from the previous number. Therefore, the correct rule for the sequence is:
Start with 3 and subtract 6 repeatedly.
Option d, "start with 3 and subtract -6 repeatedly," is also correct because subtracting a negative is the same as adding a positive. In this case, subtracting -6 is the same as adding 6. So, both options c and d are valid explanations of the rule.
