For sequences, the common difference is , and the first term is often referred to simply as "". Since you get the next term by adding the common difference, the value of is just . The third term is . The fourth term is . Following this pattern, the term an will have the form
.
For sequences, the common ratio is , and the first term is often referred to simply as "". Since you get the next term by multiplying by the common ratio, the value of is just . The third term is . The fourth term is . Following this pattern, the term an will have the form
.
in your case ,,, sequence is have the form
common difference is and the greatest common divisor is
first term is and if divided by , we get that could be written as starting with and up

so, the recursive formula is:

and this is sequence
