Xm/CV where Xm is a point of maximum error using an approximation method for x^(1/2) which I have found and CV is the population coefficient of variation from my list of error values.

COMMENTS
I am no expert at sequences, but my work is forcing me to be. I need only an equation to represent this sequence and I believe I will have completed my goal, as well as found a new approximation technique for square roots. It views them in a whole new way and should prove interesting to more formal mathematicians. This work has taken me 2.5 years and I would appreciate any help in its finalization.
a(n) = A146951(n) for 1 <= n <= 10, but more terms would be needed to justify such a hypothesis. - Georg Fischer, Nov 03 2018
FORMULA
The terms shown satisfy a(n) = 10n-4 if n is odd, a(n) = 10n-10 if n is even. - N. J. A. Sloane, Aug 15 2007
a(n) = 10*n - a(n-1) - 4, a(1)=6. - Vincenzo Librandi, Nov 23 2010
CROSSREFS
Cf. A146951.
