Q. What kind of sequence is this?54,74,94,114,…Choices:(A) arithmetic(B) geometric(C) both(D) neither
Verify Consecutive Differences Uniform: Let's verify if the differences between consecutive terms are uniform. Given sequence: 54,74,94,114,ext... Are the consecutive differences in the sequence equal? Let's calculate the differences: 74−54=20, 94−74=20, 114−94=20. The consecutive differences in the sequence are equal.
Identify Arithmetic Sequence: Since the consecutive differences are equal, this indicates that the sequence is an arithmetic sequence. An arithmetic sequence is defined by having a common difference between consecutive terms. In this case, the common difference is 20.
Check for Geometric Sequence: Now, let's check whether the sequence could also be geometric by finding the ratios between consecutive terms. Given sequence: 54,74,94,114,ext... Are the ratios between consecutive terms in the sequence equal? Let's calculate the ratios: 5474≈1.37, 7494≈1.27, 94114≈1.21. The ratios between consecutive terms are not equal.
Sequence Analysis Conclusion: Since the sequence does not have a common ratio, it is not a geometric sequence. A geometric sequence is defined by having a common ratio between consecutive terms, which is not the case here.
