1.1 Arithmetic Sequences
1.common difference=Tn-Tn-1
2.The Formula for the General Term of an Arithmetic Sequence
         The formula for the general term of an arithmetic sequence is
      Tn=T1+(n-1)d               or                  Tn=a+(n-1)d
 (explain why you add 9 not 10 common difference to find term 10)
 1.2 Arithmetic Series
1.for example.                     3,5,7,9,11————-arithmetic sequence
                                               3+5+7+9+11———arithmetic series.
Sn=n[2a+(n-1)d]/2                                                  Sn=n(a+Tn)/2
