Q. What kind of sequence is this?\newline74,59,44,29,74, 59, 44, 29, \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: 74,59,44,29,74, 59, 44, 29, \ldots\newlineAre the consecutive differences in the sequence equal? \newline5974=1559 - 74 = -15, 4459=1544 - 59 = -15, 2944=1529 - 44 = -15.\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. 5974\frac{59}{74} does not equal 4459\frac{44}{59}, nor does it equal 2944\frac{29}{44}. Therefore, the sequence does not have a common ratio.
  4. Final Sequence Classification: Since the sequence has a common difference but not a common ratio, it is an arithmetic sequence and not a geometric sequence.
