A086224 a(0) = 6, a(n+1) = 2*a(n) + 1 (or a(n)=-1+7*2^n)
6,13,27,55,111,223,447,895,1791,3583, ...
CROSSREFS
a(0) = 2 gives A055010 except for initial terms - OK (better A153893)
a(0) = 4 gives A052549 except initial terms - OK (better A153894)
a(0) = 6 gives A086224 - OK
a(0) = 8 gives A052549 except initial terms - Actually A052996
a(0) = 10 gives A086225 - OK
a(0) = 12 gives A086226 - Not in the OEIS
a(0) = 14 gives A086227 - Actually A196305
a(0) = 16 gives A086228 - Not in the OEIS
a(0) = 18 gives A086229 - Not in the OEIS
Also a(0) = 20 gives A171389
It appears some sequences may have been deleted/rejected and the A-numbers
re-used: I can correct the cross refs - but how about adding the missing
sequences?
