A sequence of numbers \(H_1\), \(H_2\), \(H_3\), … is defined as follows: \(H_1=1\) and \(H_n=H_{n-1}+6(n-1)\) for \(n \ge 2\).

- Find an expression for \(H_n\) in terms of \(n\).

Can we write \(H_n\) in terms of the previous \(H_i\)?

- Find an expression for \(H_n\) in terms of \(n\).

Can we write \(H_n\) in terms of the previous \(H_i\)?
