Full solution

Q. Type the missing number in this sequence:\newline7878, 7171, _\_, 5757, 5050
  1. Identify Pattern: Identify the pattern in the sequence.\newlineWe can see that the sequence is decreasing, so let's find the difference between the first two numbers.\newline7871=778 - 71 = 7\newlineThe sequence seems to be decreasing by 77 each time.
  2. Apply Pattern: Apply the pattern to find the missing number.\newlineIf we subtract 77 from 7171, we should get the missing number.\newline717=6471 - 7 = 64\newlineSo, the missing number should be 6464.
  3. Verify Continuation: Verify the pattern continues correctly after the missing number.\newlineNow, let's check if the sequence continues with the same pattern by adding 77 to the missing number and comparing it to the next number in the sequence.\newline64+7=7164 + 7 = 71\newline7171 is not the next number in the sequence; the next number is 5757, so we need to check our pattern again.
