Q. Complete the recursive formula of the arithmetic sequence−16,−33,−50,−67,….c(1)=□c(n)=c(n−1)+□
Identify common difference: Identify the common difference in the sequence by subtracting any term from the term that follows it. For instance, subtract −16 from −33.Calculation: −33−(−16)=−33+16=−17.Check for math errors by verifying with another pair of terms: −50−(−33)=−50+33=−17.
Calculate common difference: Since the common difference is consistent and is −17, we can write the recursive formula for the arithmetic sequence as c(n)=c(n−1)+d, where d is the common difference.Calculation: d=−17.
Substitute into formula: Substitute the common difference into the recursive formula.Calculation: c(n)=c(n−1)−17.
Find first term: The first term of the sequence, c(1), is given as −16. This is the base case for the recursive formula.Calculation: c(1)=−16.
