Which of the following is not an example of a recursive sequence?

2, 3, 6, 18,

4, 13, 22, 31,

6, 9, 15, 24,

A recursive pattern is a sequence of numbers that entails a pattern between succeeding numbers. in this case, we can see that sequence 2 has an arithmetic difference of 9, that is the proceeding terms are 40, 49, 58..  The third one has also an arithmetic difference that is increasing by 3 each. The answer then is A which has no pattern.

the person who said it was A was wrong because i clicked A and i got it wrong luckly i get another try then i clicked 4, 13, 22, 31 and it was right so the answer is 4, 13, 22,31 B
