Explanation:
Detailed explanation-1: -Complete step-by-step answer: The given sequence is 1, 3, -5, 7, 9, -11, 13, 15, -17…………. . In the given sequence, the absolute values of the terms are in arithmetic progression with a negative number appearing after every two positive terms of the sequence.
Detailed explanation-2: -Hence, from the above simplification we can see that the common difference is 2. Therefore, the general term for the sequence 1, 3, 5, 7, 9, . . . is 2n-1.
Detailed explanation-3: -This is an arithmetic sequence since there is a common difference between each term. In this case, adding 2 to the previous term in the sequence gives the next term.
Detailed explanation-4: -Answer: The sum of the arithmetic sequence is 120.
