Question

Write an expression to describe the sequence below. Use n to represent the position of a term in the sequence, where n = 1 for the first term.
-33, -66, -99, -132, ...

Answer 1

Answer:

Step-by-step explanation:

1. This is a arithmetic sequence, so the equation is $a_{n}=a_{1}+(n-1)d$.

$a_{1}$ is -33 and the d is -33.

So, the equation is $a_{n} = -33+(n-1)(-33)$.
