5. Using Recursive Rules with Sequences

Continue to next subchapter

Exercise 37 Page 447

Is it possible to find the common ratio and the first term just by looking at the explicit rule?

$a_{1} = - \frac{1}{2},$ $a_{n} = \frac{1}{4} a_{n - 1}$

Practice makes perfect

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

Recursive : Explicit : a_{n} = r \cdot a_{n - 1}; a_{1} = a_{1} a_{n} = a_{1} r^{n - 1}
