The first, fourth and tenth terms of the arithmetic sequence is
and 
Explanation:
The given rule for the arithmetic sequence is 
We need to determine the first, fourth and tenth terms of the sequence.
To find the first, fourth and tenth terms, let us substitute
in the general rule for the arithmetic sequence.
To find the first term, substitute
in
, we get,



Thus, the first term of the arithmetic sequence is -6.
To find the fourth term, substitute
in
, we get,




Thus, the fourth term of the arithmetic sequence is 
To find the tenth term, substitute
in
, we get,




Thus, the tenth term of the arithmetic sequence is 
Hence, the first, fourth and tenth terms of the arithmetic sequence is
and
