Q. For the following sequence determine the common difference (if it is an arithmetic sequence) or the common ratio (if it is a geometric sequence).4x−1,3x−1,2x−1,.. 1−xx−1
Check for Common Difference: To determine if the sequence is arithmetic or geometric, we need to check the differences or ratios between consecutive terms.First, we check if there is a common difference by subtracting the second term from the first term and the third term from the second term.
Calculate Difference: 1st & 2nd Terms: Calculate the difference between the first and second terms: (3x−1)−(4x−1)=3x−1−4x+1=−x.
Calculate Difference: 2nd & 3rd Terms: Calculate the difference between the second and third terms: (2x−1)−(3x−1)=2x−1−3x+1=−x.
Sequence is Arithmetic: Since the differences between consecutive terms are the same −x, the sequence is an arithmetic sequence with a common difference of −x.
