The next term of a sequence is made by adding the previous two terms.
Which of these sequences follow this rule?
-9 2 -7 -5 -12 -3 5 -2 3 1
0 -3 -3 0 -3. -1 -1 -2 -3 1

The first and second sequences follow the rule.
wtf
I'm sorry, did my response not make sense to you? Perhaps I can explain it better.
The rule states that the next term in the sequence is found by adding the previous two terms.
In the first sequence (-9, 2, -7, -5, -12), you can see that 2 is obtained by adding -9 and -7, and -7 is obtained by adding 2 and -9. This continues through the rest of the sequence, so it follows the rule.
In the second sequence (-3, 5, -2, 3, 1), you can see that 5 is not obtained by adding the previous two terms, since there is no negative term before it. Therefore, this sequence does not follow the rule.
In the third sequence (0, -3, -3, 0, -3), you can see that each term is the same as the term two terms before it, so it does not follow the rule either.
Finally, in the fourth sequence (-1, -1, -2, -3, 1), you can see that each term is obtained by adding the previous two terms, so it follows the rule.
