Write each series in summation notation? I would appreciate any help on this!

As for number two, I am lost on that one and would really appreciate any help. They are all factors of five, I know that much. But what would be the summation notation?

Actually, after some revision, I got 10000 Σ -10K k=1 Still stuck on number two, though..

Is my question even getting bumped? I press it but I don't see it go back up..
