Q. What kind of sequence is this?\newline169,196,225,256,169, 196, 225, 256, \dots\newlineChoices:\newline(A) arithmetic\newline(B) geometric\newline(C) both\newline(D) neither
  1. Check Arithmetic Sequence: Let's first check if the sequence is arithmetic by finding the differences between consecutive terms. \newline169,196,225,256,169, 196, 225, 256, \ldots \newlineThe differences are calculated as follows: \newline196169=27196 - 169 = 27, \newline225196=29225 - 196 = 29, \newline256225=31256 - 225 = 31. \newlineThe differences between consecutive terms are not constant.
  2. Check Geometric Sequence: Since the differences are not constant, the sequence is not arithmetic. Now, let's check if the sequence is geometric by finding the ratios between consecutive terms.\newlineThe ratios are calculated as follows:\newline196169\frac{196}{169},\newline225196\frac{225}{196},\newline256225\frac{256}{225}.\newlineWe will calculate each ratio to see if they are equal.
  3. Calculate Ratios: Calculating the ratios:\newline1961691.16\frac{196}{169} \approx 1.16,\newline2251961.15\frac{225}{196} \approx 1.15,\newline2562251.14\frac{256}{225} \approx 1.14.\newlineThe ratios between consecutive terms are not equal.
  4. Sequence Classification: Since the sequence has neither a constant difference nor a constant ratio, it is neither arithmetic nor geometric.
