The arithmetic sequence is $\"\"$ .

Now we can find the common difference d by subtracting two consecutive terms.

$\"\"$

So, the common difference $\"\"$ . $\"\"$

Now add $\"\"$ to the third term of the sequence , and then continue subtracting $\"\"$ until the next four terms are found.

Add: $\"\"$ , $\"\"$ and $\"\"$ .

The next three terms of the sequence are $\"\"$ . $\"\"$

The next three terms of the sequence are $\"\"$ .
