Exercise 20 Page 318

Use a table to organize the terms and find the pattern.

a_1=35, a_n=a_(n-1)-11

Practice makes perfect

Let's look at the given graph. The points represent terms of the sequence.

Error loading image.

The sequence is arithmetic with first term a_1=35 and common difference d=- 11. To write the recursive rule, we will substitute these values into the general formula for the recursive rule of an arithmetic sequence. la_1=a a_n=a_(n-1)+d ⇒ la_1= 35 a_n=a_(n-1) - 11</premium>
