Answer:

5, 8, 11 and 32

Step-by-step explanation:

To find any term from an nth term formula, substitute the value of the term's position for n. that is

given [tex]a_{n}[/tex] = 3n + 2, then

(a)

[tex]a_{1}[/tex] = (3 × 1) + 2 = 3 + 2 = 5

[tex]a_{2}[/tex] = (3 × 2) + 2 = 6 + 2 = 8

[tex]a_{3}[/tex] = (3 × 3) + 2 = 9 + 2 = 11

(b)

[tex]a_{10}[/tex] = (3 × 10) + 2 = 30 + 2 = 32
