Full solution

Q. {
  1. Identify the pattern: Identify the pattern in the sequence.\newlineThe given sequence is (128/27)-(128/27), (32/9)(32/9), (8/3)-(8/3). We need to determine if this is a geometric sequence and, if so, find the common ratio.
  2. Calculate the common ratio: Calculate the common ratio.\newlineTo find the common ratio, we divide the second term by the first term and the third term by the second term.\newline(329)/((12827))=(329)((27128))=13(\frac{32}{9}) / (-(\frac{128}{27})) = (\frac{32}{9}) \cdot (-(\frac{27}{128})) = -\frac{1}{3}\newline(83)/(329)=(83)(932)=13-(\frac{8}{3}) / (\frac{32}{9}) = -(\frac{8}{3}) \cdot (\frac{9}{32}) = -\frac{1}{3}\newlineThe common ratio is 13-\frac{1}{3}.
  3. Find the next term: Find the next term in the sequence.\newlineTo find the next term, we multiply the last known term by the common ratio.\newlineNext term = (83)×(13)=89-(\frac{8}{3}) \times (-\frac{1}{3}) = \frac{8}{9}
