FORMULA

a(2n+1) - a(2n-1) = 2*A091297(2n-1) + 2 . - Philippe Deléham, Feb 24 2004

a(2n) < a(2n+2) if a(2n+1) - a(2n-1) = 2; a(2n) > a(2n+2) if a(2n+1) - a(2n-1) = 4. a(n) = a(n+1) - 2 = a(n-1) + 2 iff n = 2*A036554(k) = 4*A003159(k) = A056196(k)/2. - Philippe Deléham, Feb 24 2004

PROG

(Haskell)

import Data.List (elemIndex)
