The answer to the second one is correct.
You could even say
Can't see a pattern in the first one yet.
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:
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 is possibly .
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.
Yeah, I dunno what's going on with the first one. I spent at least an hour or two going over it but it's harder then it looks...and it looked pretty hard to start with.
Oh, I also made a mistake on number one, accidently left out a number. Fixed it.
