Sn is the sum of the arithmetic sequence. A1= ? D=? An= 460 Sn= n/2 (a1+an) 8,365=35/2 (a1+ 460) 8,365= 17.5 (a1+460) 8,365= 17.5a1 + 8,050 8,365-8,050= 17.5a1 315=17.5a1 We divided it by 17.5 so the answer is 18=a1

18 is the first term. We are going to find the common difference next.

An=a1+(n-1)d 460= 18+(35-1)d 460= 18+34d 460-18=34d 442=34d We divided it by 34. So the answer is 13=D
