The answer is: No; no common difference

Here's how to determine if the sequence is an arithmetic sequence and identify the common difference:

Check for a constant difference:

Calculate the difference between subsequent terms:

-1.1 - 2.2 = -3.3

0.1 - (-1.1) = 1.2

1.3 - 0.1 = 1.2

If the difference between any two consecutive terms is constant, the sequence is arithmetic.

Identify the common difference:

If the sequence is arithmetic, the constant difference observed in step 1 is the common difference (d).

In this case:

The difference between 2.2 and -1.1 is -3.3.

The difference between -1.1 and 0.1 is 1.2.

The difference between 0.1 and 1.3 is 1.2.

Since the differences are not constant, the sequence is not arithmetic. Therefore, the answer is: No; no common difference
