Answer 2

arithmetic progression is sequence in which u find common difference same

it has,sequence

a, a+d, a+2d.........

d is called common difference

it also has property in which even numbers of terms there u will find first and last term sum equal to second and second last term sum etc

like

a1, a2, a3,a4

So a1 + a4 = a2 + a3

its general term

is an = a + ( n -1) d

examples

1,2,3. .....

has common difference 2-1 = 1 , 3-2 = 1


2,4,6,8...

has common difference 4-2 = 2

these both Are in arithmetic progression

As first series has constant common difference 1

and second series has constant difference 2
