Tell whether the sequence is arithmetic. if it is what is the common difference?
A. no
B. 1/4
C. 1/8
D. 8
My best answer is A. is that correct
You did not post the sequence
The sequence is 1, 1 1/8, 1 1/4, 1 3/8...
yes, difference is 1/8 or .125
Remark:
1 1/4 = 1 2/8
___________
1, 1 1/8, 1 1/4, 1 3/8
1 1/8 - 1 = 1/8
1 1/4 - 1 1/8 = 1 2/8 - 1 1/8 = 1/8
1 3/8 - 1 1/4 = 1 3/8 - 1 2/8 = 1/8
Common difference = 1/8
Answer C
thank you
To determine whether the sequence is arithmetic and find the common difference, we need at least three terms of the sequence. Unfortunately, you've only provided one option, so without the sequence itself, we cannot determine the correct answer.
However, I can guide you on how to determine if a sequence is arithmetic and how to find the common difference.
An arithmetic sequence is a sequence in which the difference between any two consecutive terms is constant. To check if a sequence is arithmetic, you need to compare the difference between each term with the difference between the previous term and the current term. If the differences are consistent, then the sequence is arithmetic.
To find the common difference of an arithmetic sequence, you can subtract any term from the next consecutive term. The result will be the same for all consecutive terms in an arithmetic sequence.
Without the sequence provided, I'm afraid I cannot give you the correct answer. If you provide the sequence, I'd be happy to help you determine if it is arithmetic and find the common difference.
