Question

if the n th term of an A.P is 3n + 2 ., find its common difference​

Answer 1

Answer:

Step-by-step explanation:

We are given, an= 3n+2

 So, a1= 3(1) + 2

          = 5

 and, a2= 3(2) + 2

            = 6 + 2

            = 8

 so common difference, d = a2 - a1 = 8-5

                                        = 3
