what we have to find if sum, then the answer is Step-by-step explanation:

Sn=n/2[a+l]                         an=a+(n-1)d

Sn=n/2[1+100]                      100=1+(n-1)3

S34 =34/2(101)                       100=1+3n-3

S34=17*101                                              n= 102/3

                                             n=34
