Q. What kind of sequence is this?\newline6,24,96,384,6, 24, 96, 384, \dots\newlineChoices:\newline(A) arithmetic\newline(B) geometric\newline(C) both\newline(D) neither
  1. Check Differences: Let's first check if the sequence is arithmetic by finding the differences between consecutive terms.\newlineGiven sequence: 6,24,96,384,6, 24, 96, 384, \dots\newlineDifference between the first and second term: 246=1824 - 6 = 18\newlineDifference between the second and third term: 9624=7296 - 24 = 72\newlineDifference between the third and fourth term: 38496=288384 - 96 = 288\newlineAre these differences equal?\newline187228818 \neq 72 \neq 288\newlineSince the differences are not equal, the sequence is not arithmetic.
  2. Check Ratios: Now, let's check if the sequence is geometric by finding the ratios between consecutive terms.\newlineGiven sequence: 6,24,96,384,6, 24, 96, 384, \dots\newlineRatio of the second term to the first term: 246=4\frac{24}{6} = 4\newlineRatio of the third term to the second term: 9624=4\frac{96}{24} = 4\newlineRatio of the fourth term to the third term: 38496=4\frac{384}{96} = 4\newlineAre these ratios equal?\newlineYes, the sequence has a common ratio of 44.
  3. Sequence Type: Since the sequence has a common ratio but not a common difference, we can conclude that the sequence is geometric.
