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
