Full solution

Q. Type the missing number in this sequence:\newline3,  9,  27,  ____,  243,  7293,\;9,\;27,\;\_\_\_\_,\;243,\;729
  1. Sequence Type: Is the given sequence geometric or arithmetic? Each term seems to be multiplied by a common ratio to obtain the next number. The given sequence appears to be geometric.
  2. Find Common Ratio: Find the common ratio in the geometric sequence. Two consecutive terms are 33 and 99. 93=3\frac{9}{3} = 3 Common Ratio: 33
  3. Multiply by Ratio and Find Missing Number: We multiply each term by the common ratio to get the next term. \newlineSequence: 3, 9, 27, _____, 243, 729 \newlineCommon Ratio: 33 \newlineFind the missing number in the sequence. \newlineThe number before the missing term is 2727. \newline27×3=8127 \times 3 = 81 \newlineMissing Number: 8181
