The following terms are Fibonacci numbers: a(9) = F(2), a(10)= F(4) , a(11) = F(6), a(14) = F(11); or the algebraic sum of two Fibonacci numbers: a(12) = F(8) - F(3), a(13) = F(10) - F(7), a(14) = F(12) - F(10); or the algebraic sum of three Fibonacci numbers: a(15) = F(12) + F(9) + F(5), a(16) = F(14) - F(6) - F(4), a(18) = F(16) + F(14) + F(8), a(19) = F(18) + F(10) - F(3).
