Hmmm...
I believe the ending-in-4 pattern can be explained simply by the fact 
that (n+1) is an odd multiple of 5.

I would guess without checking that many many terms of the sequence are 
congruent to -1 mod 3 as well.

And the abundance of odd terms in A085493 is explained by the fact that 
the terms + 1 are multiples of 2.

So, looking ahead we should probably eventually come across even terms 
which do not end in 4.
:)
