The justifcation of the method will be given by using the Basic Proportionality Theorem and the concept of similar triangles.

A sequence is an arrangement of numbers in a definite order according to some rule.  There are numerous ways to relate numbers to each other according to some definite rule.

If p(x) is a polynomial of degree two then p(x) = 0 form an equation and it is called a quadratic equation i.e.
