Answer:
a₂ = 13
a₃ = 11
Step-by-step explanation:
Given a₁ = 15
The recursive formula is given as: [tex]$ a_n = a_{n - 1} - 2 $[/tex]
This means that [tex]$ n^{th }[/tex] term is determined by subtracting 2 from the [tex]n -1^{th }[/tex] term.
Here, [tex]$ a_1 = 15 $[/tex]
Therefore, [tex]$ a_2 = a_1 - 2$[/tex]
= 15 - 2 = 13
Now, [tex]$ a_3 = a_2 - 2 $[/tex]
= 13 - 2 = 11
Therefore, a₂ = 13
a₃ = 11
