On reciprocal series of generalized Fibonacci numbers with subscripts in arithmetic progression
Summary: We investigate formulas for closely related series of the forms: \[ \sum^\infty_{n=0} 1/(U_{an+b} + c),\quad \sum^\infty_{n=0} (-1)^n U_{an+b}/(U_{an+b} + c)^2, \quad \sum^\infty_{n=0} U_{2(an+b)}/(U^2_{an+b} + c)^2 \] for certain values of \(a, b\), and \(c\).
