In the process of Numerical Differentiation, we differentiate an interpolating polynomial in place of ------------.

actual function

extrapolating polynomial

Lagrange’s polynomial

**Newton’s Divided Difference Interpolating polynomial**

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.

We prefer ………over the Lagrange’s interpolating method for economy of computation.
