given
then it seems you are correct.
Have you seen factorials?
Hey everyone, I have just started learning about sequences and I have found some weird notation. Here is the question (well, a similar one, I'd like to solve the actual one without help).
List the first five terms of the sequence.
I'm confused because of the set notation brackets and the fact that it doesn't say before that.
Am I correct in thinking the answer here is just 1, 2, 6, 24, 120?
