Question 999402: I have a question on this; I have tried multiple times, but cannot find the answer. Can you help?
The question is:
What is the value of the missing number?
5, 9, 16, 29, 54, (missing number), 200
If you could explain this, that would be awesome. Thanks!

Question 999996: The question reads Tell whether each sequence is an arithmetic sequence. If it is,find the common difference.
The sequence reads: 3, 5, 8, 12, 17,...
I know the sequence is +2, +3, +4, +5 but is there a way to write this as an "arithmetic sequence". All of the others were easy like "+2, -4" etc...but this oneis a bit confusing.

Question 1000816: This is at the end of our chapter where we learned about arithmetic and geometric sequences and the binomial theorem. The question is: Expand the binomial in the difference quotient and simplify. I'm given [f(x+h)-f(x)] divided by h, I'm then given f(x)=x cubed. I don't get how this relates to series, sequences, their sums, or finding the Nth term, if you could explain the connection as well, I would appreciate it so much.
