Q. What kind of sequence is this?124,140,156,172,…Choices:(A) arithmetic(B) geometric(C) both(D) neither
Verify Differences Uniform: Let's verify if the differences between consecutive terms are uniform. Given sequence: 124,140,156,172,…Are the consecutive differences in the sequence equal? 140−124=16, 156−140=16, 172−156=16.The consecutive differences in the sequence are equal.
Consecutive Differences Equal: 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.
Identify Arithmetic Sequence: Now, let's check if the sequence could also be geometric by finding the ratios between consecutive terms. 124140≈1.129, 140156≈1.114, 156172≈1.103. The ratios between consecutive terms are not equal.
Check for 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.
