I cannot figure out for the life of me how to do this. If anyone can help i would appreciate it! I need the first 3 terms and the eighth term of the sequence. Thanks

An= n!/(n-1)!

An= n!/(n-1)!
note that $\frac{n!}{(n-1)!} = n$

3. so would a1= 1?
Im confused on how to do this one because it is in a fraction form

yes, and $a_2 = 2$, $a_3 = 3$, $a_4 = 4$, ...

5. thank you so much! I get it now!!
