Question

Write an e explicit formula for an, the nth term of the sequence 22, 19, 16, ...​

Answer 1

Answer:

$a_{n} = 22 + (-3)(n - 1)$

Step-by-step explanation:

The first term is 22. It looks like each term after that is the term before, plus a negative 3.

a-sub-one  = 22

common difference = d= -3

Formula for $a_{n}$:

$a_{n} = 22 + (-3)(n - 1)$ = 25 - 3n
