Full solution

Q. What is the next term of the geometric sequence?\newline375,75,15375, 75, 15,
  1. Identify Sequence Type: Identify whether the given sequence is geometric or arithmetic.\newlineIn the given sequence, consecutive terms seem to have a common ratio because each term is smaller than the previous one by a consistent factor.
  2. Find Common Ratio: Identify the common ratio.\newlineTwo consecutive terms are 375375 and 7575.\newline75375=15\frac{75}{375} = \frac{1}{5}\newlineCommon Ratio: 15\frac{1}{5}
  3. Calculate Next Term: Find the next term in the sequence.\newlineThe last term given in the sequence is 1515.\newlineTo find the next term, multiply the last term by the common ratio.\newline15×(15)=315 \times \left(\frac{1}{5}\right) = 3
  4. Check Result Consistency: Check the result for consistency with the sequence.\newlineThe sequence is 375375, 7575, 1515, and if we have done our calculations correctly, the next term should be 33.\newlineTo check, we can see if 1515 is five times smaller than 7575, and if 33 is five times smaller than 1515.\newline755=15\frac{75}{5} = 15 and 155=3\frac{15}{5} = 3, which is consistent with our result.
