Full solution

Q. Type the missing number in this sequence:\newline55, 55, _\_, 1111, 1717, 2525, 3535
  1. Identify Pattern: Identify the pattern in the sequence.\newlineWe need to look at the differences between the numbers to see if there is a consistent pattern.\newline55 to 55 has a difference of 00.\newlineWe will need to find the difference between the other numbers once we have the missing number.
  2. Analyze Differences: Look at the differences between the known numbers in the sequence.\newline115=611 - 5 = 6\newline1711=617 - 11 = 6\newline2517=825 - 17 = 8\newline3525=1035 - 25 = 10\newlineIt seems that the difference is not consistent, but it is increasing by 22 each time after the first two numbers.
  3. Predict Missing Number: Predict the difference before the missing number. If the pattern of increasing by 22 continues, then the difference before the missing number should be 44, since the difference after it is 66.
  4. Calculate Missing Number: Calculate the missing number using the predicted difference.\newlineIf the difference before the missing number is 44, then the missing number should be 5+4=95 + 4 = 9.
  5. Verify Pattern: Verify the pattern with the calculated missing number. 5,55, 5 (difference of 00), 99 (difference of 44), 1111 (difference of 22), 1717 (difference of 66), 2525 (difference of 88), 0000 (difference of 0011). The pattern of differences is now 0022, which does not make sense. There is an inconsistency in our pattern.
