Jeremiah Peters · Answer 1

A (n) = 9 + (n - 1) * 8

2nd term ... n = 2

A2 = 9 + (2 - 1) * 8

A2 = 9 + 1 * 8

A2 = 9 + 8

A2 = 17 <==

4th term ... n = 4

A4 = 9 + (4 - 1) * 8

A4 = 9 + 3 * 8

A4 = 9 + 24

A4 = 33 <==

11th term ... n = 11

A11 = 9 + (11 - 1) * 8

A11 = 9 + 10 * 8

A11 = 9 + 80

A11 = 89 <==
