Q. Type the missing number in this sequence:\newline102102, 9797, 9292, 8787, _\_, 7777, 7272
  1. Identify Pattern: We need to identify the pattern in the sequence. By looking at the sequence, we can see that each number is 55 less than the previous number.\newlineCalculation: 97−102=−597 - 102 = -5, 92−97=−592 - 97 = -5, 87−92=−587 - 92 = -5
  2. Find Missing Number: To find the missing number, we subtract 55 from the last known number in the sequence before the missing number.\newlineCalculation: 87−5=8287 - 5 = 82
  3. Check Result: We can check our result by adding 55 to the missing number to see if we get the next number in the sequence.\newlineCalculation: 82+5=8782 + 5 = 87 (which is the number before the missing number) and 82+5=8782 + 5 = 87 (which is the number after the missing number)
