ocr: The given information is 21 = 1275, 235 = 527, - n=35 Since this is an arithmetic sequence, use the formula an == a1+ +(n-1)d to find d. 235 = a1 +(35-1)a 027-1275+(35-110 d=-22 To - find the 60th term, let n = 60. an = 21+ +(n-1)a Qso 1275+(60-11-22) Qs0 =-23 Arithmetic and Geometric Sequences
