WebThe middle term of an arithmetic sequence is the average of the arithmetic sequence. (Refer to Concept Overview given below for details) The average of the first 9 terms is the 5th term of the sequence. The sum of the first 9 terms = 252. So, average of the first 9 terms = \252 \over 9 \\) = 28. Therefore, the fifth term t 5 = 28. t 1 = 8; t 5 ... Web23 Feb 2024 · ILLUSTRATIVE EXAMPLES. A.
