Question

The sequence

Answer 1

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

$a_{n}$ = $a_{n-1}$ + 3 → with a₁ = - 2
