6. Recursively Defined Sequences
Sign In
Use a table to organize the terms and find the pattern.
a_1=1.3, a_n=a_(n-1)+1.3
The sequence is arithmetic, with first term a_1=1.3 and common difference d=1.3. 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= 1.3 a_n=a_(n-1)+ 1.3
