Q. Type the missing number in this sequence:\newline11, 33, 99, 2727, _\_, 243243
  1. Identify Sequence Type: Identify whether the given sequence is geometric or arithmetic. In the given sequence, each term appears to be a multiple of the previous term, suggesting that it is a geometric sequence.
  2. Find Common Ratio: Identify the common ratio.\newlineTo find the common ratio, we can divide a term by its preceding term. Using the second and third terms:\newline93=3\frac{9}{3} = 3\newlineCommon Ratio: 33
  3. Find Missing Number: Find the missing number.\newlineThe common ratio is 33, and the number before the missing term is 2727.\newlineTo find the next term, we multiply the last known term by the common ratio:\newline27×3=8127 \times 3 = 81\newlineMissing Number: 8181
