Arithmetic Progression Class 10 Notes- Topic 1:

Sequence: This is the ordered list of numbers.

Arithmetic progression: The list of numbers is made in such a way that each term is having a common difference in between them and the comment difference is constant, that is adding a fixed number will proceed to the next term.

The General Form of A.P-

Lets suppose a is the first term and d is the common difference in between the terms.

Now, here a₁=a

a₂=a₁+d= a + d

a₂=a₂+d= a + d + d = a + 2d

a₃=a₃+d= a + 2d + d = a + 3d

………

…………..

Moving further in the same way for “n” terms.

a_n=a +(n-1) d

Which is the nth term of an A.P. where;

a is the first term of an A.P.

n will be the number of terms and;

d is a common difference.

Sum of First n Terms of an A. P-

Now here in this scenario to get the value; considering the sum of first n terms of an A. P. is S_n.

Where,we can write the sum as follows:

S_n= (a) first term + (a+ d) second term + (a + 2d) third term +( a + 3d) third term………(1)

By putting the value of the product of ‘terms and the common difference we can write the series as:

S_n= (a +(n-1) d) +( a +(n-2) d) +(a +(n-3) d)+….+…. ………….(2)

Adding both the equation we get;

2S_n= n [2a +(n-1) d]

S_n=0.5n[2a +(n-1) d];

Where l = [a +(n-1) d]

So we can write the above equation is as follows.

S_n=0.5n[a+l]

Points to remember:

For calculating the Nth term of an AP=S_n-S_n-1

The sum of n positive integer will be calculated as S_n=n(n+1)/2

For n odd positive integers sum will be calculated as n²

For n even positive integers sum will be calculated as n(n+1)

Properties of Arithmetic Progression:

• It should be noted that if in case constant is added or subtracted or multiplied to each and every term in an AP then we get the sequence which is also followed up with a new AP.

• It should also be kept in mind that when each and every term of an AP is divided by a non-zero quantity then we get the result of a sequence of new AP.
