Final answer:
The recursive form for the given sequence {-7, -1, 5, 11, ...} is an = an-1 + 6.
Step-by-step explanation:
The given sequence is {-7, -1, 5, 11, ...}. To find the recursive form for this sequence, we need to observe the pattern in the sequence. We notice that each term is obtained by adding 6 to the previous term. Therefore, the recursive form for this sequence is:
an = an-1 + 6, where an represents the nth term of the sequence.
