An arithmetic sequence is an ordered set of numbers formed according to some pattern or rule

               {4,7,10,13,.....} The dots are ellipsis' which means that this sequence is infinite

The formula for an arithmetic sequence is

              tn=t1+d(n-1)

                t1= the first term in the sequence

                d= common difference

               n= any term in the sequence

A sequence that has a comon difference is called an arithmetic sequence

{2,4,6,8,...}

                   V V  V

                 {2,2, 2,....}   D2= 2

{1,3,5,7,9,11,13,15,...}  tn=2n-1
