The sequence is a geometric sequence:
1, 2, 6, 24, 120, 720,...
In general, the sequence can be expressed:
a%5Bn%5D+=+a%28n-1%29%2An or in words...
The nth term is equal to the previous term multiplied by n.
Let's check the 6th term (n=6):
a%5B6%5D+=+a%5B5%5D%2A6 substitute a%5B5%5D+=+120
a%5B6%5D+=+120%2A6
a%5B6%5D+=+720
Or the 4th term:
a%5B4%5D+=+a%5B3%5D%2A4 Substitute a%5B3%5D+=+6
a%5B4%5D+=+6%2A4
a%5B4%5D+=+24
