ANSWER

$f(1) = - 34$

$f(n) = f(n - 1) + 13$

EXPLANATION

The given sequence is;

-34,-21,-8,5,....

The first term of the sequence is

$f(1) = - 34$

The common difference is

$d = 5 - - 8$

$d = 5 + 8 = 13$

The recursive definition is given by;

$f(n) = f(n - 1) + d$

$f(n) = f(n - 1) + 13$

for n=2,3,4,...

There are eight boxes. Each box holds one sweater. There are 3 blue, 2 brown, 1 green, and 2 red sweaters. What is the probabili

Reil [10]

3 + 2 + 1 + 2 = 8, which is the amount of sweaters.
The probability of a brown sweater is 2 / 8 = 0.25
And the probability of a green sweater is 1 / 8 = 0.125.

Multiply the two probabilities together to get the probability of choosing brown then green:
0.25 * 0.125 = 0.03125.

To convert a decimal to fraction, you multiply the numerator and denominator, or in this case $\frac{0.03125}{1}$ by 1000 which gets $\frac{31.25}{1000}$

Which can be simplified to:
$\frac{1}{32}$ .

Hope this helps.
