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 :
[tex]a_n=a_1+d(n-1)[/tex]Here we have first term = 8 and d =9
So, the equation will be:
[tex]\begin{gathered} a_n=a_1+d(n-1) \\ a_n=8_{}+9(n-1) \end{gathered}[/tex]Answer: D)
[tex]D)a_n=8+9(n-1)[/tex]
