Q. What kind of sequence is this?\newline36,49,64,81,36, 49, 64, 81, \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: 36,49,64,81,36, 49, 64, 81, \ldots Are the consecutive differences in the sequence equal? 4936=1349 - 36 = 13, 6449=1564 - 49 = 15, 8164=1781 - 64 = 17. The consecutive differences in the sequence are not equal.
  2. Check Ratios Equality: Since the differences are not equal, the sequence is not arithmetic. Now, let's check whether the ratios between consecutive terms are equal. Given sequence: 36,49,64,81,ext...36, 49, 64, 81, ext{...} Are the ratios between consecutive terms in the sequence equal? rac{49}{36}, rac{64}{49}, rac{81}{64}. Let's calculate these ratios: rac{49}{36} hickapprox 1.3611, rac{64}{49} hickapprox 1.3061, rac{81}{64} hickapprox 1.2656. The 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 arithmetic nor geometric. Therefore, the sequence is neither arithmetic nor geometric.
