1.N=99-9%2B1=91
2. x=2n, when n=1,x=2, when n=1001,x=2002
N=1001
3.
x%5B1%5D=0
x%5B2%5D=x1%2B2%5E%282-2%29=0%2B1=1
x%5B3%5D=x%5B2%5D%2B2%5E%283-2%29=1%2B2=3
x%5B4%5D=x%5B3%5D%2B2%5E%284-2%29=3%2B4=7
x%5B5%5D=x%5B4%5D%2B2%5E%285-2%29=7%2B8=15
x%5Bn%5D=x%5Bn-1%5D%2B2%5E%28n-2%29
x%5B6%5D=31
x%5B7%5D=63
x%5B8%5D=127
x%5B9%5D=255
x%5B10%5D=511
x%5B11%5D=1023
N=11
4. I don't understand the problem. Is it x%5E2?? What does 1,3,5,7, or 99 mean?
