The given sequence:

8, 17, 26, 35

The difference between two successive number is 9

The general fromula for the explict function of airthmetic sequence is :


a_n=a_1+d(n-1)

Here we have first term = 8 and d =9

So, the equation will be:


\begin{gathered} a_n=a_1+d(n-1) \\ a_n=8_{}+9(n-1) \end{gathered}

Answer: D)


D)a_n=8+9(n-1)
