Alright, it goes hand-in-hand with a previous topic titled "Summation Formulas" but yet...it's different at the same time.

This time they give me two series:

1.

2.

My first reaction was that I would have to find the formula myself, where it starts, and where it ends. Simple...except not so much.

The second one ispossibly.

Although that would be way to simple, hehe.

The first one though, I can't seem to find a proper equation that fits the numbers given.
