Any new gravitational theories can be built with the help of a gauge theory with local Poincare symmetry. This local Poincare symmetry can set up a space-time with torsion. In the present study, the authors working on the parametrization approach towards Hubble’s parameter in the frame of modified teleparallel Gauss-Bonnet gravity which is established on the torsion invariant (Formula presented.) and the teleparallel equivalent of the Gauss-Bonnet term (Formula presented.), say (Formula presented.) gravity. In particular, gravity is responsible for an integrated explanation of the cosmological history from early-time inflation to late-time acceleration expansion, by lacking the addition of a cosmological constant. The domino effect acquired is reliable with recent cosmological outcomes. A transition scenario from a decelerating phase to an accelerating phase of cosmic evolution has been detected. Using the combined datasets (SNe-Ia+BAO+CMB+ (Formula presented.)), we have constrained the transition redshift (Formula presented.) (at which the universe transit from a decelerating phase to an accelerating) and established the best fit value of (Formula presented.). Next, we paralleled the renovated results of (Formula presented.) and (Formula presented.) and found that the outcomes are well-suited with a (Formula presented.) CDM universe.
