Please help mis amigos, thank you

Answer 3

Hint what is added to each number to get the next?

Answer 4

4

Answer 5

-3+4n?

Answer 6

yes
this is called an Arithmetic Sequence
an = a1 + (n - 1)d is the formula for the nth term of an A.S.

so plug in a1 (first term) = -3 and d (common difference) and simplify to get you answer

Answer 7

d -s what you said (4)

Answer 8

an = -3 + (n - 1)4
you need to simplify the right side

Answer 9

why would it be (n-1)?
