Arithmetic Progression

Arithmetic Progression: An arithmetic progression is a list of numbers in which each term is obtained by adding a fixed number d to the preceding term, except the first term.

Term: The fixed number d is called the common difference of the A.P.

Common Difference: Each number in the list of arithmetic progression is called term. It can be positive, negative or zero.

General form of an AP: If a is first term and d is common difference of an A.P. The general form of an AP is: a, a+d, a+2d, a+3d
(iii) ax3 + bx+ cx + d is  a polynomial of degree 3 cubic polynomial.

Finding General Term of an AP: We can find the nth term of an A.P by using Tn = a + (n-1)d
We can find the required term by putting the numeric value of n(no. of term) which we have to find from starting.
nth term from the end: l - (n-1)d where, l is the last term
