Lecture 23 meeting - Dr. Green's group - Bb... Y m University of Wir Let us consider the series n=1 (n + 47) (n + 49) Note: Write the exact answer not the decimal approximation (for example write # not 0.8). Answer: (i) Let { sn } be the sequence of partial sums. Then 97 2n+92 O sn = 2,352 n2+97n+2,352 92 2n+92 sn = 2,352 n2+92n+2,352 O sn = 92 2n+92 NO/H 2,352 n2+92n+2,352 97 2n+97 O sn = NO / H 2,352 n2+97n+2,352 (ii) If s is the sum of the series then S = Va a TT sin (a)
