Explanation opens after your attempt
A. \(a_n=6n+2\)
Concept
The first term is (8) and the difference is (6), so (a_n=8+(n-1)6=6n+2). In the general term, (d) appears with (n).
Why this answer is correct
The correct answer is A. \(a_n=6n+2\). The first term is (8) and the difference is (6), so (a_n=8+(n-1)6=6n+2). In the general term, (d) appears with (n).
