Harvey P. Dale, Table of n, a(n) for n = 1..1000
EXAMPLE
If n=13, then (p(13)-2*13)/5=(41-26)/5=3=a(1).
If n=14, then (p(14)-2*14)/5=(43-28)/5=3=a(2).
If n=17, then (p(17)-2*17)/5=(59-34)/5=5=a(3).
If n=18, then (p(18)-2*18)/5=(61-36)/5=5=a(4).
If n=22, then (p(22)-2*22)/5=(79-44)/5=7=a(5).
If n=31, then (p(31)-2*31)/5=(127-62)/5=13=a(6), etc.
