6. Recursively Defined Sequences

Continue to next subchapter

Exercise 13 Page 318

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

a_1=7, a_n=a_(n-1)+9

Practice makes perfect

To write a recursive rule for the given sequence, we will use a table to organize the terms and find the pattern.

The sequence is arithmetic, with first term a_1=7 and common difference r=9. 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= 7 a_n=a_(n-1)+ 9
