Q. What kind of sequence is this?\newline77,96,115,134,77, 96, 115, 134, \dots\newlineChoices:\newline(A) arithmetic\newline(B) geometric\newline(C) both\newline(D) neither
  1. Verify Consecutive Differences: Let's verify if the differences between consecutive terms are uniform. Given sequence: 77,96,115,134,77, 96, 115, 134, \ldots\newlineAre the consecutive differences in the sequence equal? \newline9677=1996 - 77 = 19, 11596=19115 - 96 = 19, 134115=19134 - 115 = 19.\newlineThe consecutive differences in the sequence are equal.
  2. Identify Arithmetic Sequence: Since the consecutive differences are equal, this indicates that the sequence is an arithmetic sequence. An arithmetic sequence is defined by having a common difference between consecutive terms.
  3. Check for Geometric Sequence: Now, let's check if the sequence could also be geometric by finding the ratios between consecutive terms. 9677\frac{96}{77} does not equal 11596\frac{115}{96}, and neither does it equal 134115\frac{134}{115}. Therefore, the sequence does not have a common ratio.
  4. Sequence Classification: Since the sequence has a common difference but not a common ratio, it is an arithmetic sequence and not a geometric sequence.
