Pi and self first differences

[Eric Angelini]

Hello Seqfan,
could someone check if it is possible to build
a seq where a(n)'s and their first differences
form Pi?

a(n) :     3 4 5              ???....
1st dif. :  1 1 9265358???....

Looks impossible to me... In what base could one
go the farest?
Best,
É.
