We have the following sequence of natural numbers 1, 4, 9, 13, 11, 27, 25, 37,.. . What is the next term?
Is it possible to find it with Maple? The approach
> with(gfun):
>l:=[1, 4, 9, 13, 11, 27]:
>rec:=listtorec(l,u(n));
fails because it produces a noninteger value of u(n) for some natural values of n.
