Extending Fibonacci Numbers to Negative Subscripts through Problem Solving
IJMEST Volume 41, Number 6, ISSN 0020-739X
This classroom note shows how Fibonacci numbers with negative subscripts emerge from a problem-solving context enhanced by the use of an electronic spreadsheet. It reflects the author's work with prospective K-12 teachers in a number of mathematics content courses. (Contains 4 figures.)
