State an explicit rule for the nth term of the recursively-defined sequence.
-$$a _ { n } = a _ { n - 1 } - 10 ; a _ { 1 } = 1$$
A) $a _ { n } = 10 - 1 ( n )$
B) $a _ { n } = 1 - 10 ( n - 1 )$
C) $a _ { n } = 1 - 10 ( n )$
D) $a _ { n } = 10 - 1 ( n - 1 )$

Question

Quizplus · Accepted Answer

The sequence starts at 1 and subtracts 10 for each subsequent term. The formula $a _ { n } = 1 - 10 ( n - 1 )$ correctly calculates the nth term by starting at 1 and subtracting 10 for each term beyond the first.
