Tanya Khovanova, Recursive Sequences
Index entries for linear recurrences with constant coefficients, signature (1, 1).
FORMULA
a(n) = a(n-1) + a(n-2).
G.f.: (7x + 19x^2)/(1 - x - x^2). - Emeric Deutsch, Apr 16 2005
EXAMPLE
a(3) = a(2) + a(1) = 26 + 7 = 33.
MAPLE
a[1]:=7:a[2]:=26: for n from 3 to 37 do a[n]:=a[n-1]+a[n-2] od: seq(a[n], n=1..37); # Emeric Deutsch, Apr 16 2005
