Q. Complete the recursive formula of the geometric sequence 10,6,3.6,2.16,….a(1)=a(n)=a(n−1)⋅
Identify first term: We are given the sequence: 10, 6, 3.6, 2.16, ...First, we need to identify the first term of the sequence, which is given as 10.So, a(1)=10.
Find common ratio: Next, we need to find the common ratio by dividing the second term by the first term.The common ratio r=106=0.6.
Write recursive formula: Now, we can write the recursive formula for the sequence using the first term and the common ratio.The recursive formula is a(n)=a(n−1)×r, where r is the common ratio.Substituting the value of r, we get a(n)=a(n−1)×0.6.
