I beg to differ about the objectivity of the word "better" or "best". May be we could agree upon "shorter" or " more esthetic ? " ...May be not.

To continue series 1,4.... what is "better"?

a 1,4,7,10,...............arithmetic series

b 1,4,16,64...............geometric

c 1,4,9,16,25,............squares

d 1,4,11,44,111,444.......ones on odd places,fours on even

e 1,4,9,61,52,............squares inverted

f 1,4,11,22,37............a(n)= 2n^2-3n+2

g 1,4,9,22,49............a(n)= n^3-5n^2+11n-6

h 1,4,5,9,14,............fibo with 1,4 initialization etc

etc

In the above series only 2 samples were given. However I wanted to illustrate the folllowing fact: ONE CANNOT DEFINE A SERIES UNAMBIGUOUSLY BY PROVIDING SOME OF ITS MEMBERS.

Please look up SLOANE on the web and try to get definition for any series of yours( SLOANE asks for some 30 numbers!!-)

I hope you agree with me.
