Q. Type the missing number in this sequence:\newline11, 22, 44, _____, 1616
  1. Identify Sequence Type: Is the given sequence geometric or arithmetic? Each term appears to be multiplied by a common ratio to obtain the next number. The given sequence is likely geometric.
  2. Find Common Ratio: Find the common ratio in the geometric sequence. Two consecutive terms are 11 and 22. 21=2\frac{2}{1} = 2 Common Ratio: 22
  3. Multiply by Ratio: We multiply each term by the common ratio to get the next term. \newlineSequence: 1,2,4,____,161, 2, 4, \_\_\_\_, 16 \newlineCommon Ratio: 22 \newlineFind the missing number in the sequence. \newlineThe number before the missing term is 44. \newline4×2=84 \times 2 = 8 \newlineMissing Number: 88
