THE NUMBER OF ATTENDANCE QUESTIONS WERE:

PLEASE LIST ALL THE QUESTIONS FOLLOWED, AFTER EACH BY THE ANSWER
Question 1
Let K be the 3-digit number consisting of your 3rd,4th,5th RUID digits
What is g(K)?
Answer
g(500)=[1,0,1]

Question 2
Is {g(n)} in the OEIS? If yes what is the A-number if not should be?
Answer
A000793
I have no clue but i guess so since the OEIS is supposed to recorded all possible number combinations 

Question 3
For i=3,4,5,....
Compute 
(seqRec([1$i],[o$(i-1),1],30);
Find wether these sequences are in the oeis
Find their A-numbers
What is the smallest i for which this sequence is not in the OEIS?
Should it be?
Answer
A000045
i=2
yes

Question 4
LET #a:=2nd digit of YOUR RUID(it is 0 make 1) b:=7th digit
#what is the 100th term of GFseq(1/1-x^a-x^b)
Answer
1/(1-x^6-x^1)
GFseq:=proc(f,x,N) local f1,i:
f1:=taylor(f,x=o,N+1):
[seq(coeff(f1,x,i),i=0..N)]:
end:

GFseq(1/(1-x^6-x),x,10);
I put in this code but it wont seem to work. I keep get that it is 
unable to compute coeff.
