Reviewer 4 Report

The fact that beta is upper bounded by 1/s is enough to obtain the convergence of the sequence, the Cauchy property and even the fact that the limit of the sequence is a fixed point of T. So the property of beta function is not needed in the proof of the results.

Dear Prof ...

Thank you for your useful comments and suggestions.

‎According to assuming $s\geq 1$‎.

‎If $s> 1$‎, ‎then we have‎

‎$d(x_n,x_{n+1})<\dfrac{1}{s}d(x_{n-1},x_{n}),$ where $\frac{1}{s}<1$‎. ‎So we concluded that $\{x_n\}$ is a Cauchy sequence‎.

‎But‎, ‎while $s=1$‎, ‎we have $d(x_n,x_{n+1})<d(x_{n-1},x_{n})$‎. ‎Then $\{x_n\}$ is a nonincreasing sequence.

‎Best Regard‎s.
