Q. What kind of sequence is this?34,29,24,19,…Choices:(A) arithmetic(B) geometric(C) both(D) neither
Verify Consecutive Differences: Let's verify if the differences between consecutive terms are uniform. Given sequence: 34,29,24,19,…Are the consecutive differences in the sequence equal? 29−34=−5, 24−29=−5, 19−24=−5. The consecutive differences in the sequence are equal and the common difference is −5.
Identify Arithmetic Sequence: Since the sequence has a common difference, it is an arithmetic sequence. An arithmetic sequence is defined by having a constant difference between consecutive terms.
Check for Geometric Sequence: Now, let's check if the sequence could also be geometric by finding the ratios between consecutive terms. 3429 does not equal 2924, nor does it equal 2419. The ratios between consecutive terms are not equal, so the sequence is not geometric.
Final Conclusion: Based on the above steps, we can conclude that the sequence is arithmetic because it has a common difference, and it is not geometric because it does not have a common ratio.
