Q. Find the common ratio of the geometric sequence 19,95,475,…Answer:
Identify Pattern: Identify the pattern in the sequence to determine if it is geometric.The sequence provided is 19, 95, 475, which suggests that each term is a multiple of the previous term. This indicates that the sequence is likely geometric.
Calculate Ratio: Calculate the ratio between the second and the first term to find the common ratio.The second term is 95 and the first term is 19. To find the common ratio, we divide the second term by the first term.Common ratio = 1995
Perform Division: Perform the division to find the common ratio. 95 divided by 19 equals 5. Common ratio = 5
Verify Common Ratio: Verify the common ratio by checking if the third term is a product of the second term and the common ratio.The third term is 475 and the second term is 95. Multiply the second term by the common ratio to see if it equals the third term.95×5=475This confirms that the common ratio is correct.
