Q. What is the next term of the geometric sequence?5,15,45
Identify Sequence Type: Identify whether the given sequence is geometric or arithmetic.In the given sequence, each term after the first is obtained by multiplying the previous term by a constant number, which suggests that the sequence is geometric.
Find Common Ratio: Identify the common ratio of the geometric sequence.To find the common ratio, divide the second term by the first term, or the third term by the second term.515=31545=3Common Ratio: 3
Find Next Term: Find the next term in the sequence.To find the next term, multiply the last known term by the common ratio.45×3=135Next Term: 135
