Q. Type the missing number in this sequence:\newline____\_\_\_\_, 7676, 7070, 6464, 5858
  1. Identify Pattern: Identify the pattern in the sequence.\newlineThe sequence provided is 76,70,64,5876, 70, 64, 58. We need to determine if the sequence is arithmetic (where the difference between terms is constant) or geometric (where the ratio between terms is constant).\newlineBy subtracting consecutive terms, we can check for an arithmetic sequence:\newline7076=670 - 76 = -6\newline6470=664 - 70 = -6\newline5864=658 - 64 = -6\newlineThe differences are all 6-6, indicating an arithmetic sequence with a common difference of 6-6.
  2. Find Missing Number: Find the missing number in the sequence.\newlineSince the sequence is arithmetic with a common difference of 6-6, we can find the missing number by adding the common difference to the first known term, 7676.\newlineTo find the term before 7676, we subtract the common difference from 7676:\newlineMissing number = 76(6)=76+6=8276 - (-6) = 76 + 6 = 82
  3. Verify Solution: Verify the solution.\newlineTo ensure that the missing number is correct, we can check if the pattern continues correctly after inserting the found number:\newline82,76,70,64,5882, 76, 70, 64, 58\newline7682=676 - 82 = -6\newline7076=670 - 76 = -6\newline6470=664 - 70 = -6\newline5864=658 - 64 = -6\newlineThe differences are all 6-6, which confirms that the pattern is consistent and the missing number is correct.
