Geometry

Ok it's me again. I'm am working on problems that involve describing number patterns. I've figured them all out but two.

Here are the two strings or numbers

7,9,13,19,27,;;;;

and

256, 16, 4, 2

Any help?

    7+2=9+4=13+6=19+8=27 and so on. Basically it starts by adding 2 then for each next one it adds 2 so plus 2 then plus 4 and so on.
    256 divided by 8=16 divided by 4=4 divided by 2=2 for this one the amount divided keeps getting cut down by 50%. Hope I helped. =)
