Arithmetic Progression

Arithmetic Progression

1. Definition

   • List of numbers in which each term is obtained by adding a fixed number to the preceding term except the first term. Fixed number is called common difference.

2. General Form

   • a, a +d, a +2d, a +3d ... +(

3. Common Difference

4. N th term

5. Arithmetic mean

6. Sum (s)

7. Definition

   • List of numbers in which each term is obtained by adding a fixed number to the preceding term except the first term. Fixed number is called common difference

8. General Form

   • a,a+d,a+2d,a+3d......a+(n-1)d

9. Common Difference

   • •Fixed number in arithmetic progression which provides the to and fro terms by adding/subtracting from the present number. •Can be positive or negative.

10. Nth term

    • Term=a+(n-1)d

11. Sum (s)

    • Sum=n/2{a+(n-1)d}

12. Arithmetic mean

    • b = (a+ c)/2
