Me: 
Also we read in "hints":

http://www.research.att.com/~njas/sequences/hints.html
 
 "If your sequence has an obvious common factor (e.g.
2 6 12 20 30 42 ...) try dividing it out and look up 1
3 6 10 15 21 instead."

In view of this, shouldn't we remove, e.g.,  

A097697 = A049422/2, and 
A083022 = A028873/2
?!
I see in OEIS many sequences  of the forms
A1 -/+ const, A1/const, A1*const, etc.

Though, sure, some of them may be of (some) essence.
