c

to generate the first four terms, substitute n = 1, 2, 3, 4 into the formula

[tex]a_{1}[/tex] = (3 × 1) + 5 = 3 + 5 = 8

[tex]a_{2}[/tex] = (3 × 2 ) + 5 = 6 + 5 = 11

[tex]a_{3}[/tex] = (3 × 3) + 5 = 9 + 5 = 14

[tex]a_{4}[/tex] = (3 × 4) + 5 = 12 + 5 = 17

the first four terms are 8, 11, 14, 17 → c
