1 point


​

Answer 1

Answer:

common difference = 3

Step-by-step explanation:

Tn =  3n -1

1st term of the A.P. = T1  =  3(1) -1

                                        =  3 -1

                                         = 2

2nd term of the A.P. = T2 = 3(2) -1

                                            = 6 - 1

                                            = 5

Commom difference = T2 - T1

                                   =  5 - 2

                                   =    3
