What is the next number in the sequence?

1, 4, 13, 40, 121 ... ?

Thank you for the help!

Looks like the next term in the sequence is generated by multiplying the previous term by 3 and adding 1:


1*3+1=4

4*3+1=13

13*3+1=40

40*3+1=121

If the pattern holds, the next term is probably going to be


121*3+1=364
