Answer 1

a₂ = 13

a₃ = 11

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
