Answer:

a_{n} = - 3a_{n-1}

Step-by-step explanation:

There is a common ratio between consecutive terms of the sequence, that is

r = 9 ÷ - 3 = - 27 ÷ 9 = 81 ÷ - 27 = - 243 ÷ 81 = - 3

The recursive formula is of the form

a_{n} = ra_{n-1} = - 3a_{n-1}

Nostrana [21]

Answer:

<h2>\frac{3x + 25}{5 {x}^{2} }</h2>

Step-by-step explanation:

\frac{x + 5}{ {x}^{2} }  -  \frac{2}{5x}

Write all the numbers above the least common denominator {5x}^{2}

\frac{5(x + 5) - 2x}{5 {x}^{2} }

Distribute 5 through the parentheses

\frac{5x + 25 - 2x}{5 {x}^{2} }

Collect like terms

\frac{3x + 25}{5 {x}^{2} }

Hope this helps...

Good luck on your assignment...
