What is the d value of the following arithmetic sequence?
5, 2, -1, -4, -7,…
A. 3
B. -3
C. 4
D. -4
To find the d value of an arithmetic sequence, you need to determine the common difference between consecutive terms. The common difference is the value added or subtracted from each term to get to the next term in the sequence.
In this arithmetic sequence: 5, 2, -1, -4, -7,...
To find the common difference (d), you can subtract any term from the following term. Let's subtract the second term (2) from the first term (5).
5 - 2 = 3
Therefore, the common difference (d) of this arithmetic sequence is 3.
So, the correct answer is:
A. 3
