Q. Find the common difference of the arithmetic sequence 4,2,0,…Answer:
Subtract consecutive terms: To find the common difference of an arithmetic sequence, subtract any term from the term that follows it.Calculation: 2−4=−2
Check consistency: Check the difference with another pair of consecutive terms to ensure consistency.Calculation: 0−2=−2
Determine common difference: Since the difference is consistent, the common difference of the arithmetic sequence is −2.
