$a_{1} = \frac{2}{5}$ ; $a_{n} = 5 a_{n - 1}$

Step 1

Rewrite the equation as $5 a_{n - 1} = a_{n}$ .

$5 a_{n - 1} = a_{n}$

$a_{1} = \frac{2}{5}$

Step 2

Subtract $5 a_{n - 1}$ from both sides of the equation.

$0 = a_{n} - 5 a_{n - 1}$

$a_{1} = \frac{2}{5}$

Step 3

Rewrite the equation as $a_{n} - 5 a_{n - 1} = 0$ .

$a_{n} - 5 a_{n - 1} = 0$

$a_{1} = \frac{2}{5}$
