Hi Candidate,

Let's know about the General Procedure of Newton's Backward Method- Newton's Backward Method is the way of approximating a function with an n ^th degree polynomial passing through (n+1) equally spaced points.

Here, in this question the value of X1 is 5.5 and the value of x0 is 3.456, where a s = (x - x ₁ ) / (x ₁ - x ₀ ) and Ñf ₁ is the backward difference of f at x ₁ .

Hope that this answer helps you.
