**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.__

*Arithmetic Progression*__•__

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

*Term*•

__:__

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

(iii) ax

•

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

*: 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*__General form of an AP__(iii) ax

^{3 }+ bx^{2 }+ cx + d is a polynomial of degree 3 cubic polynomial.•

__: We can find the nth term of an A.P by using T__*Finding General Term of an AP*_{n}= a + (n-1)dWe can find the required term by putting the numeric value of n(no. of term) which we have to find from starting.
