dude im helping and no one helps me
1-a
2-b
both are correct.
thanks bob finally!!!!!!!
To determine whether the given number sequences are arithmetic, geometric, both, or neither, we need to analyze the patterns between the terms.
For the sequence 7, 9, 11, 13..., we can observe that each term is obtained by adding 2 to the previous term. This pattern indicates that the sequence is increasing by a constant difference, so it is an arithmetic sequence. Therefore, the correct answer is A) arithmetic.
Now, let's move on to the second sequence 2, 1, 1/2, 1/4.... In this case, each term is obtained by dividing the previous term by 2. This means that each term is half of its previous term, indicating that the sequence is decreasing by a constant ratio. Hence, the pattern suggests that this sequence is a geometric sequence. Therefore, the correct answer is B) geometric.
