    Richardson extrapolation is method also known as …………

    Sequence acceleration method
    Series acceleration method

    Ref
    In numerical analysis, Richardson extrapolation is a sequence acceleration method, used to improve the rate of convergence of a sequence. It is named after Lewis Fry Richardson, who introduced the technique in the early 20th century.
