Question

A recursive function is shown below:  f(1) = 4 and f(n) = f(n - 1) - 8; n > 1  Which of the following lists the terms in the sequence defined by this recursive function?   4, -4, -12, -20, -28, ...   4, 4, 12, 20, 28, ...   4, 12, 20, 28, 36, ...   4, -12, -20, -28, -36, ...

anonymous · Answer

the sequence starts with 8, The next term is 8 less than the previous one so, the second term should be 4-8 = -4. Does it make sense?
