Answer:
The common difference of the given arithmetic sequence is:
-7
Step-by-step explanation:
We know that the common difference of the arithmetic sequence is a fixed constant by which each number in the sequence is differ from the preceding term.
Here we have sequence as:
25 , 18 , 11 , 4 ,.......
Hence, the common difference is calculated as:
18-25= -7
11-18= -7
4-11= -7
Hence, the common difference of the given arithmetic sequence is:
-7
