Let’s check out your problem:

Which recursive formula can be used to define this sequence for n > 1?$\newline$$15, 14, 13, 12, 11, 10, \ldots$$\newline$Choices:$\newline$(A) $a_{n} = a_{n-1} - 1$$\newline$(B) $a_{n} = -1a_{n-1}$$\newline$(C) $a_{n} = a_{n-1} + a_{n-1} - 1$$\newline$(D) $a_{n} = \frac{14}{15}a_{n-1}$
