Q. g(n)=−50−15nComplete the recursive formula of g(n).g(1)=g(n)=g(n−1)+
Identify first term: Identify the first term of the sequence using the given explicit formulag(n)=−50−15n by substituting n=1.Calculation: g(1)=−50−15(1)=−50−15=−65.
Determine common difference: Determine the common difference between consecutive terms by calculating the difference g(2)−g(1).Calculation: g(2)=−50−15(2)=−50−30=−80, and g(1)=−65, so the common difference is −80−(−65)=−15.
Write recursive formula: Write the recursive formula using the first term and the common difference. The recursive formula has the form g(n)=g(n−1)+d, where d is the common difference.Calculation: Since the common difference is −15, the recursive formula is g(n)=g(n−1)−15.
