Q. What kind of sequence is this?50,50,50,50,…Choices:(A) arithmetic(B) geometric(C) both(D) neither
Check for Arithmetic Sequence: Let's first check if the sequence is an arithmetic sequence by determining if there is a common difference between consecutive terms. Given sequence: 50,50,50,50,ext... Are the consecutive differences in the sequence equal? 50−50=0, 50−50=0, 50−50=0. The consecutive differences in the sequence are equal and the common difference is 0.
Check for Geometric Sequence: Now, let's check if the sequence is a geometric sequence by determining if there is a common ratio between consecutive terms. Given sequence: 50,50,50,50,ext... Are the ratios between consecutive terms in the sequence equal? 50/50=1, 50/50=1, 50/50=1. The sequence has a common ratio of 1.
Arithmetic Sequence Definition: An arithmetic sequence is defined as a sequence with a constant difference between consecutive terms. Since the difference here is 0, it satisfies the definition of an arithmetic sequence.
Geometric Sequence Definition: A geometric sequence is defined as a sequence with a constant ratio between consecutive terms. Since the ratio here is 1, it satisfies the definition of a geometric sequence.
Sequence is Both Arithmetic and Geometric: Since the sequence satisfies the definitions of both an arithmetic and a geometric sequence, the correct answer is that the sequence is both arithmetic and geometric.
