5. Using Recursive Rules with Sequences

Continue to next subchapter

Exercise 45 Page 448

Is it possible find the common difference and the first term just by looking at the recursive rule?

$a_{n} = 9.1 n - 21.1$

Practice makes perfect

The explicit rule of an arithmetic sequence combines the information provided by the two equations of the recursive rule into a single equation.

Recursive : Explicit : a_{n} = a_{n - 1} + d; a_{1} = a_{1} a_{n} = a_{1} + (n - 1) d
