### HOGATT-HANSELL-TYPE IDENTITIES OF ODD NUMBERS

#### Abstract

This paper is a kind of investigatory project that can be modeled by students in the basic education doing mathematical research. The results established here may be incorporated in the instructional materials for teaching function and sequence. The number o(n,k) for positive integers n and k from the pyramid of odd numbers

*φn*is introduced and some Hogatt-Hansell-type identities are established and discussed.#### Keywords

pyramid of odd numbers, explicit formula, Hogatt-Hansell-type identity
