The parametric form of the Hubble parameter is, $H\\left(z\\right) =H_{0}\\left[ \\alpha +\\left( 1-\\alpha \\right) \\left( 1+z\\right) ^{n}\\right] ^{\\frac{3}{2n}}$, where $H_0$ and $n$ are constants and for $n=3$, the $\\Lambda$CDM scenario can be obtained. We have considered the logarithmic form of $f(Q,T)$ as, $f(Q,T)=-Q+\\beta \\log\\left(\\frac{Q}{Q_{0}}\\right)+\\gamma T$, where $\\beta $ and $\\gamma $ are the free model parameters.
