Hi, I was just looking at this problem with sequences and I was having a question about factorials.(adsbygoogle = window.adsbygoogle || []).push({});

I understand that the factorials need to get smaller.

I was just wondering what is the (3)(2)(1) in the problem symbolizing?

Just that it will eventually reach the end? and what numbers are 3 2 1?

is it 3n? or -3?

just getting confused here.

Its only half the problem, but I understand what needs to be done for the sequence, just the factorial part was the problem.

heres the pic:
