Generalized sum of Pell Numbers [PDF]
, 2021 Here we are proposing a generalized sum for Pell numbers. This sum contains four Pell numbers. By means of this generalized sum, the Pell number at position (n+m) in the sequence is given by the Pell numbers at positions n, m, (n-1) and (m-1)

Equations with arithmetic functions of Pell numbers [PDF]
, 2014 Here, we prove some diophantine results about the Euler function of Pell numbers and their Pell-Lucas companion sequence. For example, if the Euler function of the nth Pell number Pn or Pell- Lucas companion number Qn is a power of 2, then n is greater ...

From Probation to Partnership: Building Equitable Systems of Support in Community Colleges
New Directions for Community Colleges, EarlyView.ABSTRACT Community colleges serve as critical gateways to higher education for diverse student populations, yet traditional academic probation systems often exacerbate inequities by penalizing students facing systemic and personal challenges. This practitioner–scholar case study examines Clark State College's Academic Engagement Program (AEP), an ...

Pell Leonardo numbers and their matrix representations
Journal of New Results in ScienceIn this study, we investigate Pell numbers and Leonardo numbers and describe a new third-order number sequence entitled Pell Leonardo numbers. We then construct some identities, including the Binet formula, generating function, exponential generating ...

Beyond the Classroom at Dallas College: Documenting a Framework for Student Parents’ College Success
New Directions for Community Colleges, EarlyView.ABSTRACT Student parents make up a substantial share of community college enrollment, yet the support that exists is often dispersed across offices. In this article, we review and summarize research on the importance of student services for community college student parents.

Governing Sponge City Transitions: Policy Objectives and Socio‐Technical Change
Environmental Policy and Governance, EarlyView.ABSTRACT In theory, climate adaptation policy cycles can be framed as being harmonized and goal‐oriented governance processes. Yet any examination of climate adaptation in cities reveals persistent tensions between this logic and the diverse forces shaping adaptation in practice.

On hyperbolic k-Pell quaternions sequences [PDF]
Annales Mathematicae et Informaticae, 2018 Summary: In this paper we introduce the hyperbolic $k$-Pell functions and new classes of quaternions associated with this type of functions are presented. In addition, the Binet formulas, generating functions and some properties of these functions and quaternions sequences are studied.

A New Approach to k-Jacobsthal Lucas Sequences
Sakarya Üniversitesi Fen Bilimleri Enstitüsü Dergisi, 2021 In this study, 〖CS〗_(k,n) of S_(k,n) Catalan transformation of 𝑘−Jacobsthal-Lucas sequences is defined. S_(k,n) Catalan transformation of 𝑘−Jacobsthal-Lucas S_(k,n) sequences is obtained.In addition the transformation of CS_(k,n) is written as the ...
