Question 1039350: Hello! In this problem, I had some trouble: "Find the value of t(subscript 2) + t(sub3) + t(sub4) + ... + t(sub 98) if t (sub 1) + t (sub 2) t (sub 3)... is an arithmetic progression with the common difference = 1, and S (sub 98) = 137.
Please help me on this one. I've screwed up two solutions of it already...

Question 1039330: Hello ! I need help with this problem. At first I thought I had solved it, but then whoops, I calculated 3 means instead of 5, and upon looking closer, I discovered that my whole process was utterly wrong... I looked at my book for help, but it didn't really make me understand anything. So here's the question: Insert 5 arithmetic means between (x+3y) and (9y-5x). I'll appreciate any help, thanks!

Question 1039332: Hey! So I was finishing up homework when yet another problem had me crying. After hours of trying to do it on my own, I decided to ask for help. Okay, so If 5x+2, 2x^2 + 8, 24x - x^2 form an arithmetic sequence, find x and the 12th term. I'm stumped trying to solve this. I literally have no idea. I tried subtracting the first term from the second to get the common difference, but hey, when I tried subtracting the third term from the second one, the "common" differences were not so common. Maybe the given is wrong? I don't know...
