As a consequence, we obtain that all sequences ?$F_n^{(r)}$? of hyperfibonacci numbers of ?$r$?-th generation are log-concave for ?$r \ge 1$? and large enough ?$n$?TEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaUniverza na Primorskem, Fakulteta za naravoslovje, matematiko in informacijske tehnologije
