Question
Tell whether the given sequence is an arithmetic sequence. 48,45,42,39,....
Hint:
- A sequence is said to be arithmetic if the common difference is always constant.
- The General formula of any AP is
.
.The correct answer is: ⇒-3
Explanation:
- We have given a sequence 48,45,42,39,...
- We have to find weather the given sequence is AP or not.
Step 1 of 1:
We have given sequence 48,45,42,39,...
The difference in first two terms is
Now the difference in next two terms is
Then, The difference between next two terms will be
Since the difference is constant
The given sequence is an arithmetic sequence.
Now the difference in next two terms is
Then, The difference between next two terms will be
Since the difference is constant
The given sequence is an arithmetic sequence.
