Query: Dynamics of quasi de Sitter and linear combination of exponential models
  in extended gravity   In this paper, we have studied the dynamical aspects of some cosmological
models in an isotropic space-time within the framework of an extended gravity
theory. Two accelerating cosmological models are presented with quasi-de Sitter
(QDS) and linear combination of exponential (LCE) scale factors. The
geometrical testing mechanism has been performed and analysed. While the
results of the QDS model show a departure from the concordant $\Lambda$CDM
model, the resulting behavior of the LCE model seems to be compatible with the
$\Lambda$CDM model only at the present epoch and is incompatible in the near
past.
