Q. Type the missing number in this sequence:\newline____\_\_\_\_, 22, 1212, 2222, 3232
  1. Identify Pattern: First, let's try to identify a pattern in the given sequence. We can do this by subtracting the second number from the third number, then the third number from the fourth number, and so on. If the differences are the same, then the sequence is an arithmetic sequence.\newlineCalculation: 12−2=1012 - 2 = 10, 22−12=1022 - 12 = 10, 32−22=1032 - 22 = 10
  2. Calculate Differences: From the above step, we can see that the difference between each pair of consecutive numbers is 1010. This means that the sequence is an arithmetic sequence with a common difference of 1010.
  3. Common Difference: To find the missing number, we can subtract the common difference from the second number in the sequence.\newlineCalculation: 2−10=−82 - 10 = -8
