Q. Type the missing number in this sequence:\newline81,  87,  93,  99,  _____,  11181,\;87,\;93,\;99,\;\_\_\_\_\_,\;111
  1. Identify Pattern: We need to determine the pattern in the sequence. By looking at the differences between the numbers, we can identify the pattern.\newline87−81=687 - 81 = 6\newline93−87=693 - 87 = 6\newline99−93=699 - 93 = 6\newlineThe pattern is that each number is 66 more than the previous number.
  2. Find Missing Number: To find the missing number, we add 66 to the last known number in the sequence, which is 9999. \newline99+6=10599 + 6 = 105
  3. Confirm Answer: We can check our answer by adding 66 to the missing number we found, 105105, to see if it equals the next number in the sequence, which is 111111. \newline105+6=111105 + 6 = 111\newlineThis confirms that our pattern is correct and that the missing number is indeed 105105.
