Answer:
22, 19, 16 and - 5
Step-by-step explanation:
To evaluate any term from the n th term formula substitute the terms position value for n
given [tex]a_{n}[/tex] = 25 - 3n, then
(a)
[tex]a_{1}[/tex] = 25 - (3 × 1) = 25 - 3 = 22
[tex]a_{2}[/tex] = 25 - (3 × 2) = 25 - 6 = 19
[tex]a_{3}[/tex] = 25 - (3 × 3) = 25 - 9 = 16
(b)
[tex]a_{10}[/tex] = 25 - (3 × 10) = 25 - 30 = - 5
