Answer 1

Answer:

a₂ = 13

a₃ = 11

Step-by-step explanation:

Given a₁ = 15

The recursive formula is given as:  $a_n = a_{n - 1} - 2$

This means that $n^{th }$ term is determined by subtracting 2 from the $n -1^{th }$ term.

Here, $a_1 = 15$

Therefore, $a_2 = a_1 - 2$

= 15 - 2 = 13

Now, $a_3 = a_2 - 2$

= 13 - 2 = 11

Therefore, a₂ = 13

a₃ = 11
