hi, i'm unable to get the pattern for the sequence: 2,4,11,36,147,778,.. I even checked in oeis.org but it doesn't have it. Could someone please help in determining how the terms are related to each other in this sequence?

Thanks.

Hello, pranay!

Are there typos?

With a different first term and sixth term, I have a pattern.

Quote:

Sequence: .1, 4, 11, 36, 147, 738 . . .

$\displaystyle a_{n+1} \:=\:n\:\!a_n + 3$

It's a

I came across this problem on SPOJ.I first guessed the factorial part.And the rest could be found on OEIS.
