Q. Find the common ratio of the geometric sequence 15,90,540, 15,-90,540, \ldots \newlineAnswer:
  1. Find Common Ratio: To find the common ratio of a geometric sequence, we divide any term by the previous term. Let's divide the second term by the first term to find the common ratio. Common ratio rr = (90)/15(-90) / 15
  2. Calculate Common Ratio: Now, let's perform the calculation:\newliner=(90)/15r = (-90) / 15\newliner=6r = -6
  3. Check Consistency: To ensure that 6-6 is indeed the common ratio, we should check if the third term divided by the second term also equals 6-6. Let's check: 540/(90)540 / (-90)
  4. Check Consistency: To ensure that 6-6 is indeed the common ratio, we should check if the third term divided by the second term also equals 6-6. Let's check: 540/(90)540 / (-90) Performing the calculation for the check: 540/(90)=6540 / (-90) = -6 This confirms that the common ratio is consistent across these terms.
