Answer:
A
Step-by-step explanation:
Note that consecutive terms have a common difference, that is
1 - (- 2) = 4 - 1 = 7 - 4 = 10 - 7 = 3
This indicates that the sequence is arithmetic with d = 3
The next term in the sequence is obtained by adding 3 to the previous term
This can be expressed recursively as
[tex]a_{n}[/tex] = [tex]a_{n-1}[/tex] + 3 → with a₁ = - 2
