Q. What kind of sequence is this?\newline144,169,196,225,144, 169, 196, 225, \ldots\newlineChoices:\newline(A) arithmetic\newline(B) geometric\newline(C) both\newline(D) neither
  1. Verify Differences Uniform: Let's verify if the differences between consecutive terms are uniform. Given sequence: 144,169,196,225,144, 169, 196, 225, \ldots\newlineAre the consecutive differences in the sequence equal? \newline169144=25169 - 144 = 25, 196169=27196 - 169 = 27, 225196=29225 - 196 = 29.\newlineThe consecutive differences in the sequence are not equal, but they are increasing by 22 each time.
  2. Check Ratios Equality: Since the differences are not constant, the sequence is not arithmetic. Now let's check whether the ratios between consecutive terms are equal.\newlineGiven sequence: 144,169,196,225,144, 169, 196, 225, \ldots\newlineAre the ratios between consecutive terms in the sequence equal? \newline1691441.1736\frac{169}{144} \approx 1.1736, 1961691.1598\frac{196}{169} \approx 1.1598, 2251961.1480\frac{225}{196} \approx 1.1480.\newlineThe ratios between consecutive terms are not equal.
  3. Sequence Classification: Since the sequence has neither a common difference nor a common ratio, it is neither an arithmetic sequence nor a geometric sequence.
