Answer 2

Answer:

A.P is Arithmetic Progression

Step-by-step explanation:

A.P is Arithmetic Progression

For example: 1

1,2,3,4....... n terms are in A.P because their common difference is 1.

Example: 2

2,4,6,8,.......n are said to be in A.P because their common difference is 2. i.e

Let, 1st term a1 = 2,

2nd term a2=4

and so on

their common difference (d) = a2 - a1 = 4-2=2
