8,12,18,27,...

First of all I know that i can make a polynomial or whatever function pass through these points but I make a relation I just want to build the general term of it

I took the difference between any two terms

I choose 40

8 , 12 , 18 , 27 , 40 , 58.

4 , 6 , 9 ,13 , 18

2 , 3 ,4 , 5

1 , 1 , 1

so first row is constant second is n+1

but third how I can make it .

thanks
