Q. What kind of sequence is this?50,55,60,65,…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: 50,55,60,65,…Are the consecutive differences in the sequence equal? 55−50=5, 60−55=5, 65−60=5.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.
Check for Geometric Sequence: Now, let's check if the sequence could also be geometric by finding the ratios between consecutive terms. 5055=1.1, 5560=1.0909…, 6065=1.0833…The ratios between consecutive terms are not equal.
Confirm Not Geometric Sequence: 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.
