Here we will create a sequence of problems for equations of type (1) (see on the next page). These sequenced problems are appropriate for the fostering of talented students on different level of mathematical education.application/pdfsequenced problemsfunctional equationsfolyóiratcikkOpen AccessZsolt Ádám, Károly Lajkó, Gyula Maksa and Fruzsina Mészároshttps://doi.org/10.5485/TMCS.2006.0126Teaching Mathematics and Computer Science14Teach.
