The first, fourth and tenth terms of the arithmetic sequence is  and
 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.
 in the general rule for the arithmetic sequence.
To find the first term, substitute  in
 in  , we get,
 , we get,



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




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




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