Q. Complete the recursive formula of the geometric sequence 300,60,12,2.4,…d(1)=d(n)=d(n−1)⋅
Identify First Term: Identify the first term of the sequence.The first term of the sequence is given as 300.
Determine Common Ratio: Observe the pattern to determine the common ratio.The sequence is 300, 60, 12, 2.4, ... To find the common ratio, divide the second term by the first term: 30060=0.2
Write Recursive Formula: Write the recursive formula using the first term and the common ratio.The recursive formula for a geometric sequence is given by:d(n)=d(n−1)×r, where r is the common ratio.Here, d(1)=300 and r=0.2.So, the recursive formula is d(n)=d(n−1)×0.2.
